VARIoT IoT vulnerabilities database

D-LinkDSL-6850U is a wireless router product of D-Link. D-LinkDSL-6850U Router Remote Command Execution Vulnerability. Since the router has the remote web management service enabled by default, the service has the default credentials support:support and cannot be disabled. The attacker can log in to the router's web management interface through the default credentials, and then manually open the Wan port telnet service that is turned off by default. After logging in to the telnet service, you can use the && or || command sandbox escape to get full shell permissions.

An Improper Input Validation issue was discovered in Advantech WebAccess versions prior to 8.3. WebAccess allows some inputs that may cause the program to crash. Advantech WebAccess Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. The vulnerability is caused by a failure to properly validate WebAccess input. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple denial-of-service vulnerabilities 2. Multiple stack-based buffer-overflow vulnerabilities 3. A directory-traversal vulnerability 4. An SQL-injection vulnerability 5. Multiple denial-of-service vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and obtain sensitive information

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Meltdown vulnerability exists in the CPU processor core, which \"melts\" the security boundary implemented by hardware, allowing low-privileged user-level applications to \"cross-border\" access to system-level memory, causing data leakage. The following products and versions are affected: ARM Cortex-R7; Cortex-R8; Cortex-A8; Cortex-A9; Cortex-A12; Xeon CPU E5-1650 v3, v2, v4; Xeon E3-1265l v2, v3, v4 ; Xeon E3-1245 v2, v3, v5, v6 versions; Xeon X7542, etc. ========================================================================== Ubuntu Security Notice USN-3597-2 March 15, 2018 linux-hwe vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS Summary: Several security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS. USNS 3541-2 and 3523-2 provided mitigations for Spectre and Meltdown (CVE-2017-5715, CVE-2017-5753, CVE-2017-5754) for the i386, amd64, and ppc64el architectures for Ubuntu 16.04 LTS. This flaw is known as Meltdown. This flaw is known as Spectre. (CVE-2017-5715, CVE-2017-5753) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.13.0-37-generic 4.13.0-37.42~16.04.1 linux-image-4.13.0-37-generic-lpae 4.13.0-37.42~16.04.1 linux-image-4.13.0-37-lowlatency 4.13.0-37.42~16.04.1 linux-image-generic-hwe-16.04 4.13.0.37.56 linux-image-generic-lpae-hwe-16.04 4.13.0.37.56 linux-image-lowlatency-hwe-16.04 4.13.0.37.56 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. Summary: An update for kernel is now available for Red Hat Enterprise Linux 5.9 Long Life. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Long Life (v. 5.9 server) - i386, ia64, noarch, x86_64 3. Security Fix(es): An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. Please refer to References section for further information about this issue and the performance impact. In this update mitigations for x86-64 architecture are provided. * Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5753, Important) * Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important) Red Hat would like to thank Google Project Zero for reporting these issues. Bug Fix(es): * Previously, the page table isolation feature was able to modify the kernel Page Global Directory (PGD) entries with the _NX bit even for CPUs without the capability to use the "no execute" (NX) bit technology. Consequently, the page tables got corrupted, and the kernel panicked at the first page-fault occurrence. This update adds the check of CPU capabilities before modifying kernel PGD entries with _NX. As a result, the operating system no longer panics on boot due to corrupted page tables under the described circumstances. (BZ#1538169) * When booting the operating system with the Kernel Page Table Isolation option enabled, the HPET VSYSCALL shadow mapping was not placed correctly. Consequently, the High Precision Event Timer (HPET) feature was not available early enough, and warnings on boot time occurred. This update fixes the placement of HPET VSYSCALL, and the warnings on boot time due to this behavior no longer occur. (BZ#1541281) * Previously, the routine preparing the kexec crashkernel area did not properly clear the page allocated to be kexec's Page Global Directory (PGD). Consequently, the page table isolation shadow mapping routines failed with a warning message when setting up page table entries. With this update, the underlying source code has been fixed to clear the kexec PGD allocated page before setting up its page table entries. As a result, warnings are no longer issued when setting up kexec. (BZ#1541285) * When changing a kernel page mapping from Read Only (RO) to Read Write (RW), the Translation Lookaside Buffer (TLB) entry was previously not updated. Consequently, a protection fault on a write operation occurred, which led to a kernel panic. With this update, the underlying source code has been fixed to handle such kind of fault properly, and the kernel no longer panics in the described situation. (BZ#1541892) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.

CVE-2015-9016 Ming Lei reported a race condition in the multiqueue block layer (blk-mq). On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the "retpoline" compiler feature which allows indirect branches to be isolated from speculative execution. CVE-2017-5753 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function. More use sites will be added over time. CVE-2017-13166 A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space. On a 64-bit kernel a local user with access to a suitable video device can exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2017-13220 Al Viro reported that the Bluetooth HIDP implementation could dereference a pointer before performing the necessary type check. A local user could use this to cause a denial of service. CVE-2017-16526 Andrey Konovalov reported that the UWB subsystem may dereference an invalid pointer in an error case. A local user might be able to use this for denial of service. CVE-2017-16911 Secunia Research reported that the USB/IP vhci_hcd driver exposed kernel heap addresses to local users. This information could aid the exploitation of other vulnerabilities. CVE-2017-16912 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to an out-of-bounds read. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-16913 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to excessive memory allocation. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-16914 Secunia Research reported that the USB/IP stub driver failed to check for an invalid combination of fields in a received packet, leading to a null pointer dereference. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-18017 Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module failed to validate TCP header lengths, potentially leading to a use-after-free. If this module is loaded, it could be used by a remote attacker for denial of service or possibly for code execution. CVE-2017-18203 Hou Tao reported that there was a race condition in creation and deletion of device-mapper (DM) devices. A local user could potentially use this for denial of service. CVE-2017-18216 Alex Chen reported that the OCFS2 filesystem failed to hold a necessary lock during nodemanager sysfs file operations, potentially leading to a null pointer dereference. A local user could use this for denial of service. CVE-2017-18232 Jason Yan reported a race condition in the SAS (Serial-Attached SCSI) subsystem, between probing and destroying a port. This could lead to a deadlock. A physically present attacker could use this to cause a denial of service. CVE-2017-18241 Yunlei He reported that the f2fs implementation does not properly initialise its state if the "noflush_merge" mount option is used. A local user with access to a filesystem mounted with this option could use this to cause a denial of service. CVE-2018-1066 Dan Aloni reported to Red Hat that the CIFS client implementation would dereference a null pointer if the server sent an invalid response during NTLMSSP setup negotiation. This could be used by a malicious server for denial of service. CVE-2018-1068 The syzkaller tool found that the 32-bit compatibility layer of ebtables did not sufficiently validate offset values. On a 64-bit kernel, a local user with the CAP_NET_ADMIN capability (in any user namespace) could use this to overwrite kernel memory, possibly leading to privilege escalation. Debian disables unprivileged user namespaces by default. CVE-2018-1092 Wen Xu reported that a crafted ext4 filesystem image would trigger a null dereference when mounted. A local user able to mount arbitrary filesystems could use this for denial of service. CVE-2018-5332 Mohamed Ghannam reported that the RDS protocol did not sufficiently validate RDMA requests, leading to an out-of-bounds write. A local attacker on a system with the rds module loaded could use this for denial of service or possibly for privilege escalation. CVE-2018-5333 Mohamed Ghannam reported that the RDS protocol did not properly handle an error case, leading to a null pointer dereference. A local attacker on a system with the rds module loaded could possibly use this for denial of service. CVE-2018-5750 Wang Qize reported that the ACPI sbshc driver logged a kernel heap address. This information could aid the exploitation of other vulnerabilities. CVE-2018-5803 Alexey Kodanev reported that the SCTP protocol did not range-check the length of chunks to be created. A local or remote user could use this to cause a denial of service. CVE-2018-6927 Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did not check for negative parameter values, which might lead to a denial of service or other security impact. CVE-2018-7492 The syzkaller tool found that the RDS protocol was lacking a null pointer check. A local attacker on a system with the rds module loaded could use this for denial of service. CVE-2018-7566 Fan LongFei reported a race condition in the ALSA (sound) sequencer core, between write and ioctl operations. This could lead to an out-of-bounds access or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-7740 Nic Losby reported that the hugetlbfs filesystem's mmap operation did not properly range-check the file offset. A local user with access to files on a hugetlbfs filesystem could use this to cause a denial of service. CVE-2018-7757 Jason Yan reported a memory leak in the SAS (Serial-Attached SCSI) subsystem. A local user on a system with SAS devices could use this to cause a denial of service. CVE-2018-7995 Seunghun Han reported a race condition in the x86 MCE (Machine Check Exception) driver. This is unlikely to have any security impact. CVE-2018-8781 Eyal Itkin reported that the udl (DisplayLink) driver's mmap operation did not properly range-check the file offset. A local user with access to a udl framebuffer device could exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2018-8822 Dr Silvio Cesare of InfoSect reported that the ncpfs client implementation did not validate reply lengths from the server. An ncpfs server could use this to cause a denial of service or remote code execution in the client. CVE-2018-1000004 Luo Quan reported a race condition in the ALSA (sound) sequencer core, between multiple ioctl operations. This could lead to a deadlock or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-1000199 Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings. Local users can use this to cause a denial of service, or possibly for privilege escalation, on x86 (amd64 and i386) and possibly other architectures.

(CVE-2017-5754, Important) Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Spectre vulnerability exists in the CPU processor core. Because Intel does not separate low-privileged applications from accessing kernel memory, an attacker can use a malicious application to obtain private data that should be quarantined. Intel and ARM CPU chips have an information disclosure vulnerability, which originates from a flaw in the processor data boundary mechanism. The following products and versions are affected: ARM Cortex-A75; Intel Xeon E5-1650 v3, v2, v4; Xeon E3-1265l v2, v3, v4; Xeon E3-1245 v2, v3, v5, v6; Xeon X7542 wait. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2018-1-23-2 macOS High Sierra 10.13.3, Security Update 2018-001 Sierra, and Security Update 2018-001 El Capitan macOS High Sierra 10.13.3, Security Update 2018-001 Sierra, and Security Update 2018-001 El Capitan are now available and address the following: Audio Available for: macOS High Sierra 10.13.2, macOS Sierra 10.12.6 Impact: Processing a maliciously crafted audio file may lead to arbitrary code execution Description: A memory corruption issue was addressed through improved input validation.

By now, we're sure most everyone have heard of the Meltdown and Spectre attacks. If not, head over to https://meltdownattack.com/ and get an overview. https://googleprojectzero.blogspot.com/2018/01/reading-privileged-memory-with-side.html The FreeBSD Security Team was notified of the issue in late December and received a briefing under NDA with the original embargo date of January 9th. Since we received relatively late notice of the issue, our ability to provide fixes is delayed. Meltdown (CVE-2017-5754) ~~~~~~~~~~~~~~~~~~~~~~~~ In terms of priority, the first step is to mitigate against the Meltdown attack (CVE-2017-5754, cited as variant 3 by Project Zero). Work for this is ongoing, but due to the relatively large changes needed, this is going to take a little while. We are currently targeting patches for amd64 being dev complete this week with testing probably running into next week. From there, we hope to give it a short bake time before pushing it into the 11.1-RELEASE branch. Additional work will be required to bring the mitigation to 10.3-RELEASE and 10.4-RELEASE. The code will be selectable via a tunable which will automatically turn on for modern Intel processors and off for AMD processors (since they are reportedly not vulnerable). Since the fix for Meltdown does incur a performance hit for any transition between user space and kernel space, this could be rather impactful depending on the workload. As such, the tunable can also be overridden by the end-user if they are willing to accept the risk. Initial work can be tracked at https://reviews.freebsd.org/D13797. Please note this is a work in progress and some stuff is likely to be broken. Spectre (CVE-2017-5753 and CVE-2017-5715) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When it comes to the Spectre vulnerabilities, it is much harder to sort these out. Variant 1 (CVE-2017-5753) is going to require some static analysis to determine vulnerable use cases that will require barriers to stop speculation from disclosing information it shouldn't. While we haven't done the analysis to determine where we are vulnerable, the number of cases here are supposed to be pretty small. Apparently there have been some Coverity rules developed to help look for these, but we are still evaluating what can be done here. The other half of Spectre, variant 2 (CVE-2017-5715) is a bit trickier as it affects both normal processes and bhyve. There is a proposed patch for LLVM (https://reviews.llvm.org/D41723) that introduces a concept called 'retpoline' which mitigates this issue. We are likely to pull this into HEAD and 11-STABLE once it hits the LLVM tree. Unfortunately, the currently supported FreeBSD releases are using older versions of LLVM for which we are not sure the LLVM project will produce patches. We will be looking at the feasibility to backport these patches to these earlier versions. There are CPU microcode fixes coming out when in concert with OS changes would also help, but that's a bit down the road at the moment.

Ubuntu will provide corresponding QEMU updates in the future for users of self-hosted virtual environments in coordination with upstream QEMU. Ubuntu users in cloud environments should contact the cloud provider to confirm that the hypervisor has been updated to expose the new CPU features to virtual machines. Bug Fix(es): * Previously, the page table isolation feature was able to modify the kernel Page Global Directory (PGD) entries with the _NX bit even for CPUs without the capability to use the "no execute" (NX) bit technology. Consequently, the page tables got corrupted, and the kernel panicked at the first page-fault occurrence. This update adds the check of CPU capabilities before modifying kernel PGD entries with _NX. As a result, the operating system no longer panics on boot due to corrupted page tables under the described circumstances. (BZ#1538169) * When booting the operating system with the Kernel Page Table Isolation option enabled, the HPET VSYSCALL shadow mapping was not placed correctly. Consequently, the High Precision Event Timer (HPET) feature was not available early enough, and warnings on boot time occurred. This update fixes the placement of HPET VSYSCALL, and the warnings on boot time due to this behavior no longer occur. (BZ#1541281) * Previously, the routine preparing the kexec crashkernel area did not properly clear the page allocated to be kexec's Page Global Directory (PGD). Consequently, the page table isolation shadow mapping routines failed with a warning message when setting up page table entries. With this update, the underlying source code has been fixed to clear the kexec PGD allocated page before setting up its page table entries. As a result, warnings are no longer issued when setting up kexec. (BZ#1541285) * When changing a kernel page mapping from Read Only (RO) to Read Write (RW), the Translation Lookaside Buffer (TLB) entry was previously not updated. Consequently, a protection fault on a write operation occurred, which led to a kernel panic. With this update, the underlying source code has been fixed to handle such kind of fault properly, and the kernel no longer panics in the described situation. (BZ#1541892) 4.

Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. Please refer to References section for further information about this issue and the performance impact. In this update mitigations for x86-64 architecture are provided. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5753, Important) Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important) Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important) Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. Red Hat would like to thank Google Project Zero for reporting these issues. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.

Intel has now identified the root cause of these issues and determined that these microcodes may introduce reboots and other unpredictable system behavior. Due to the severity of the potential issues that may occur when using these microcodes, Intel is now recommending that customers discontinue their use. Additional information is available from Intels Security Exploit Newsroom here: <https://newsroom.intel.com/press-kits/security-exploits-intel-products/> . HPE is in alignment with Intel in our recommendation that customers discontinue use of System ROMs including impacted microcodes and revert to earlier System ROM versions. All System ROMs including impacted microcodes have been removed from the HPE Support Site. This impacts HPE ProLiant and Synergy Gen10, Gen9, and Gen8 v2 servers as well as HPE Superdome servers for which updated System ROMs had previously been made available. Intel is working on updated microcodes to address these issues, and HPE will validate updated System ROMs including these microcodes and make them available to our customers in the coming weeks. Mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown) vulnerabilities require only OS updates and are not impacted. * HPE has provided a customer bulletin <https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00039267en_us> with specific instructions to obtain the udpated sytem ROM - Note: + CVE-2017-5715 (Variant 2) requires that the System ROM be updated and a vendor supplied operating system update be applied as well. + For CVE-2017-5753, CVE-2017-5754 (Variants 1 and 3) require only updates of a vendor supplied operating system. + HPE will continue to add additional products to the list.

A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header. Cisco Node-jose Library is prone to a remote security-bypass vulnerability. Attackers can exploit this issue to bypass certain security restrictions to gain unauthorized access. This may aid in further attacks

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". Has speculative execution function and out-of-order execution function CPU Several researchers have reported methods of performing side-channel attacks against Has speculative execution function and out-of-order execution function CPU side-channel attack method against (Spectre and Meltdown) has been reported. For more information, Google Project Zero blog post in ("Reading privileged memory with a side-channel") or Graz University of Technology (TU Graz) information from researchers in ("Meltdown and Spectre") Please refer to. "Reading privileged memory with a side-channel"https://googleprojectzero.blogspot.jp/2018/01/reading-privileged-memory-with-side.html"Meltdown and Spectre"https://meltdownattack.com/Sensitive information can be obtained from processes running with user privileges. Spectre As for the attack, crafted Javascript by the code Javascript cannot be obtained from web It has been reported that data can be obtained during the browser process. CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Meltdown vulnerability exists in the CPU processor core, which \"melts\" the security boundary implemented by hardware, allowing low-privileged user-level applications to \"cross-border\" access to system-level memory, causing data leakage. Multiple CPU Hardware are prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in further attacks.

Description: Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM. (CVE-2017-5715) Note: This is the qemu-kvm side of the CVE-2017-5715 mitigation. Once all virtual machines have shut down, start them again for this update to take effect. Relevant releases/architectures: Image Updates for RHV-H - noarch 3. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. Security Fix(es): An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. Please refer to References section for further information about this issue and the performance impact. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important) Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important) Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. Red Hat would like to thank Google Project Zero for reporting these issues. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information from other domains, bypassing same-origin restrictions. Summary: An update for linux-firmware is now available for Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 7.2 Advanced Update Support, Red Hat Enterprise Linux 7.2 Telco Extended Update Support, Red Hat Enterprise Linux 7.2 Update Services for SAP Solutions, and Red Hat Enterprise Linux 7.3 Extended Update Support.

Description: The linux-firmware packages contain all of the firmware files that are required by various devices to operate. This update supersedes microcode provided by Red Hat with the CVE-2017-5715 (aSpectrea) CPU branch injection vulnerability mitigation. (Historically, Red Hat has provided updated microcode, developed by our microprocessor partners, as a customer convenience.) Further testing has uncovered problems with the microcode provided along with the aSpectrea mitigation that could lead to system instabilities. As a result, Red Hat is providing an microcode update that reverts to the last known good microcode version dated before 03 January 2018. Red Hat strongly recommends that customers contact their hardware provider for the latest microcode updates. IMPORTANT: Customers using Intel Skylake-, Broadwell-, and Haswell-based platforms must obtain and install updated microcode from their hardware vendor immediately. The "Spectre" mitigation requires both an updated kernel from Red Hat and updated microcode from your hardware vendor. 4.

At the request of Intel, we have reverted to the previous packaged microcode version, the 20170707 release. This flaw is known as Spectre. (CVE-2017-5715) This update provides the microcode updates required for the corresponding Linux kernel updates. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: intel-microcode 3.20180108.0+really20170707ubuntu17.10.1 Ubuntu 16.04 LTS: intel-microcode 3.20180108.0+really20170707ubuntu16.04.1 Ubuntu 14.04 LTS: intel-microcode 3.20180108.0+really20170707ubuntu14.04.1 After a standard system update you need to reboot your computer to make all the necessary changes

The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Linux Kernel Contains a vulnerability in the use of freed memory.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Linux Kernel is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition. Linux kernel versions prior to 4.11, and 4.9.x prior to 4.9.36 are vulnerable. 6) - i386, x86_64 3. Red Hat would like to thank Google Project Zero for reporting CVE-2017-5754; Nick Peterson (Everdox Tech LLC) and Andy Lutomirski for reporting CVE-2018-8897; Mohamed Ghannam for reporting CVE-2017-8824; and Armis Labs for reporting CVE-2017-1000410. Bug Fix(es): These updated kernel packages include also numerous bug fixes. Space precludes documenting all of these bug fixes in this advisory. See the bug fix descriptions in the related Knowledge Article: https://access.redhat.com/articles/3431591 4. Security Fix(es): * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639) Note: This issue is present in hardware and cannot be fully fixed via software update. To be fully functional, up-to-date CPU microcode applied on the system might be required. Bugs fixed (https://bugzilla.redhat.com/): 1531135 - CVE-2017-18017 kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c 1566890 - CVE-2018-3639 hw: cpu: speculative store bypass 6. 7) - noarch, x86_64 3.

CVE-2015-9016 Ming Lei reported a race condition in the multiqueue block layer (blk-mq). On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the "retpoline" compiler feature which allows indirect branches to be isolated from speculative execution. CVE-2017-5753 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function. More use sites will be added over time. CVE-2017-13166 A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space. On a 64-bit kernel a local user with access to a suitable video device can exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2017-13220 Al Viro reported that the Bluetooth HIDP implementation could dereference a pointer before performing the necessary type check. A local user could use this to cause a denial of service. CVE-2017-16526 Andrey Konovalov reported that the UWB subsystem may dereference an invalid pointer in an error case. A local user might be able to use this for denial of service. CVE-2017-16911 Secunia Research reported that the USB/IP vhci_hcd driver exposed kernel heap addresses to local users. This information could aid the exploitation of other vulnerabilities. CVE-2017-16912 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to an out-of-bounds read. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-16913 Secunia Research reported that the USB/IP stub driver failed to perform a range check on a received packet header field, leading to excessive memory allocation. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-16914 Secunia Research reported that the USB/IP stub driver failed to check for an invalid combination of fields in a received packet, leading to a null pointer dereference. A remote user able to connect to the USB/IP server could use this for denial of service. CVE-2017-18017 Denys Fedoryshchenko reported that the netfilter xt_TCPMSS module failed to validate TCP header lengths, potentially leading to a use-after-free. If this module is loaded, it could be used by a remote attacker for denial of service or possibly for code execution. CVE-2017-18203 Hou Tao reported that there was a race condition in creation and deletion of device-mapper (DM) devices. A local user could potentially use this for denial of service. CVE-2017-18216 Alex Chen reported that the OCFS2 filesystem failed to hold a necessary lock during nodemanager sysfs file operations, potentially leading to a null pointer dereference. A local user could use this for denial of service. CVE-2017-18232 Jason Yan reported a race condition in the SAS (Serial-Attached SCSI) subsystem, between probing and destroying a port. This could lead to a deadlock. CVE-2017-18241 Yunlei He reported that the f2fs implementation does not properly initialise its state if the "noflush_merge" mount option is used. A local user with access to a filesystem mounted with this option could use this to cause a denial of service. CVE-2018-1066 Dan Aloni reported to Red Hat that the CIFS client implementation would dereference a null pointer if the server sent an invalid response during NTLMSSP setup negotiation. This could be used by a malicious server for denial of service. CVE-2018-1068 The syzkaller tool found that the 32-bit compatibility layer of ebtables did not sufficiently validate offset values. On a 64-bit kernel, a local user with the CAP_NET_ADMIN capability (in any user namespace) could use this to overwrite kernel memory, possibly leading to privilege escalation. Debian disables unprivileged user namespaces by default. CVE-2018-1092 Wen Xu reported that a crafted ext4 filesystem image would trigger a null dereference when mounted. A local user able to mount arbitrary filesystems could use this for denial of service. CVE-2018-5332 Mohamed Ghannam reported that the RDS protocol did not sufficiently validate RDMA requests, leading to an out-of-bounds write. A local attacker on a system with the rds module loaded could use this for denial of service or possibly for privilege escalation. CVE-2018-5333 Mohamed Ghannam reported that the RDS protocol did not properly handle an error case, leading to a null pointer dereference. A local attacker on a system with the rds module loaded could possibly use this for denial of service. CVE-2018-5750 Wang Qize reported that the ACPI sbshc driver logged a kernel heap address. This information could aid the exploitation of other vulnerabilities. CVE-2018-5803 Alexey Kodanev reported that the SCTP protocol did not range-check the length of chunks to be created. A local or remote user could use this to cause a denial of service. CVE-2018-6927 Li Jinyue reported that the FUTEX_REQUEUE operation on futexes did not check for negative parameter values, which might lead to a denial of service or other security impact. CVE-2018-7492 The syzkaller tool found that the RDS protocol was lacking a null pointer check. A local attacker on a system with the rds module loaded could use this for denial of service. CVE-2018-7566 Fan LongFei reported a race condition in the ALSA (sound) sequencer core, between write and ioctl operations. This could lead to an out-of-bounds access or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-7740 Nic Losby reported that the hugetlbfs filesystem's mmap operation did not properly range-check the file offset. A local user with access to files on a hugetlbfs filesystem could use this to cause a denial of service. CVE-2018-7757 Jason Yan reported a memory leak in the SAS (Serial-Attached SCSI) subsystem. A local user on a system with SAS devices could use this to cause a denial of service. CVE-2018-7995 Seunghun Han reported a race condition in the x86 MCE (Machine Check Exception) driver. This is unlikely to have any security impact. CVE-2018-8781 Eyal Itkin reported that the udl (DisplayLink) driver's mmap operation did not properly range-check the file offset. A local user with access to a udl framebuffer device could exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2018-8822 Dr Silvio Cesare of InfoSect reported that the ncpfs client implementation did not validate reply lengths from the server. An ncpfs server could use this to cause a denial of service or remote code execution in the client. CVE-2018-1000004 Luo Quan reported a race condition in the ALSA (sound) sequencer core, between multiple ioctl operations. This could lead to a deadlock or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-1000199 Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings.

On Hoermann BiSecur devices before 2018, a vulnerability can be exploited by recording a single radio transmission. An attacker can intercept an arbitrary radio frame exchanged between a BiSecur transmitter and a receiver to obtain the encrypted packet and the 32-bit serial number. The interception of the one-time pairing process is specifically not required. Due to use of AES-128 with an initial static random value and static data vector (all of this static information is the same across different customers' installations), the attacker can easily derive the utilized encryption key and decrypt the intercepted packet. The key can be verified by decrypting the intercepted packet and checking for known plaintext. Subsequently, an attacker can create arbitrary radio frames with the correct encryption key to control BiSecur garage and entrance gate operators and possibly other BiSecur systems as well ("wireless cloning"). To conduct the attack, a low cost Software Defined Radio (SDR) is sufficient. This affects Hoermann Hand Transmitter HS5-868-BS, HSE1-868-BS, and HSE2-868-BS devices.
