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. 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2018-1-8-3 Safari 11.0.2 Safari 11.0.2 is now available and and addresses the following: Available for: OS X El Capitan 10.11.6 and macOS Sierra 10.12.6 Description: Safari 11.0.2 includes security improvements to mitigate the effects of Spectre (CVE- 2017-5753 and CVE-2017-5715). We would like to acknowledge Jann Horn of Google Project Zero; and Paul Kocher in collaboration with Daniel Genkin of University of Pennsylvania and University of Maryland, Daniel Gruss of Graz University of Technology, Werner Haas of Cyberus Technology, Mike Hamburg of Rambus (Cryptography Research Division), Moritz Lipp of Graz University of Technology, Stefan Mangard of Graz University of Technology, Thomas Prescher of Cyberus Technology, Michael Schwarz of Graz University of Technology, and Yuval Yarom of University of Adelaide and Data61 for their assistance. Installation note: Safari 11.0.2 may be obtained from the Mac App Store. 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.

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.

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. 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.

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. 6.6) - noarch, x86_64 3. Security Fix(es): * hw: cpu: speculative execution permission faults handling (CVE-2017-5754) * Kernel: error in exception handling leads to DoS (CVE-2018-8897) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * If an NFSv3 client mounted a subdirectory of an exported file system, a directory entry to the mount hosting the export was incorrectly held even after clearing the cache. Consequently, attempts to unmount the subdirectory with the umount command failed with the EBUSY error. With this update, the underlying source code has been fixed, and the unmount operation now succeeds as expected in the described situation. (BZ#1538588) * The kernel build requirements have been updated to the GNU Compiler Collection (GCC) compiler version that has the support for Retpolines. The Retpolines mechanism is a software construct that leverages specific knowledge of the underlying hardware to mitigate the branch target injection, also known as Spectre variant 2 vulnerability described in CVE-2017-5715. (BZ#1554254) 4. On i386 and amd64 architectures, the IBRS and IBPB features are required to enable the kernel mitigations. Ubuntu is working with Intel and AMD to provide future microcode updates that implement IBRS and IBPB as they are made available. Ubuntu users with a processor from a different vendor should contact the vendor to identify necessary firmware updates. 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Note: the current version of the following document is available here: https://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-hpesbhf03805en_us SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: hpesbhf03805en_us Version: 5 HPESBHF03805 rev.5 - Certain HPE products using Microprocessors from Intel, AMD, and ARM, with Speculative Execution, Elevation of Privilege and Information Disclosure.

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. In this update initial mitigations for IBM Power (PowerPC) and IBM zSeries (S390) architectures are provided. * 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. This fix specifically addresses S390 processors. (CVE-2017-5715, Important) * 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. This fix specifically addresses S390 and PowerPC processors. (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. Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. This fix specifically addresses PowerPC processors. (CVE-2017-5754, Important) Red Hat would like to thank Google Project Zero for reporting CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754.

Corrected: 2018-02-17 18:00:01 UTC (stable/11, 11.1-STABLE) 2018-03-14 04:00:00 UTC (releng/11.1, 11.1-RELEASE-p8) CVE Name: CVE-2017-5715, CVE-2017-5754 Special Note: Speculative execution vulnerability mitigation is a work in progress. This advisory addresses the most significant issues for FreeBSD 11.1 on amd64 CPUs. We expect to update this advisory to include 10.x for amd64 CPUs. Future FreeBSD releases will address this issue on i386 and other CPUs. freebsd-update will include changes on i386 as part of this update due to common code changes shared between amd64 and i386, however it contains no functional changes for i386 (in particular, it does not mitigate the issue on i386). For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. II. Problem Description A number of issues relating to speculative execution were found last year and publicly announced January 3rd. Two of these, known as Meltdown and Spectre V2, are addressed here. CVE-2017-5754 (Meltdown) - ------------------------ This issue relies on an affected CPU speculatively executing instructions beyond a faulting instruction. When this happens, changes to architectural state are not committed, but observable changes may be left in micro- architectural state (for example, cache). This may be used to infer privileged data. CVE-2017-5715 (Spectre V2) - -------------------------- Spectre V2 uses branch target injection to speculatively execute kernel code at an address under the control of an attacker. III. Impact An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser). IV. Workaround No workaround is available. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility, followed by a reboot into the new kernel: # freebsd-update fetch # freebsd-update install # shutdown -r now 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. [FreeBSD 11.1] # fetch https://security.FreeBSD.org/patches/SA-18:03/speculative_execution-amd64-11.patch # fetch https://security.FreeBSD.org/patches/SA-18:03/speculative_execution-amd64-11.patch.asc # gpg --verify speculative_execution-amd64-11.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in <URL:https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the system. VI. Correction details CVE-2017-5754 (Meltdown) - ------------------------ The mitigation is known as Page Table Isolation (PTI). PTI largely separates kernel and user mode page tables, so that even during speculative execution most of the kernel's data is unmapped and not accessible. A positive result is definitive (that is, the vulnerability exists with certainty). A negative result indicates either that the CPU is not affected, or that the test is not capable of demonstrating the issue on the CPU (and may need to be modified). A patched kernel will automatically enable PTI on Intel CPUs. The status can be checked via the vm.pmap.pti sysctl: # sysctl vm.pmap.pti vm.pmap.pti: 1 The default setting can be overridden by setting the loader tunable vm.pmap.pti to 1 or 0 in /boot/loader.conf. This setting takes effect only at boot. PTI introduces a performance regression. The observed performance loss is significant in microbenchmarks of system call overhead, but is much smaller for many real workloads. CVE-2017-5715 (Spectre V2) - -------------------------- There are two common mitigations for Spectre V2. This patch includes a mitigation using Indirect Branch Restricted Speculation, a feature available via a microcode update from processor manufacturers. The alternate mitigation, Retpoline, is a feature available in newer compilers. The feasibility of applying Retpoline to stable branches and/or releases is under investigation. The patch includes the IBRS mitigation for Spectre V2. To use the mitigation the system must have an updated microcode; with older microcode a patched kernel will function without the mitigation. IBRS can be disabled via the hw.ibrs_disable sysctl (and tunable), and the status can be checked via the hw.ibrs_active sysctl. IBRS may be enabled or disabled at runtime. Additional detail on microcode updates will follow. The following list contains the correction revision numbers for each affected branch.

Software Description: - linux: Linux kernel Details: It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System (f2fs) in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-0750) It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-0861) It was discovered that the KVM implementation in the Linux kernel allowed passthrough of the diagnostic I/O port 0x80. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2017-1000407) Bo Zhang discovered that the netlink wireless configuration interface in the Linux kernel did not properly validate attributes when handling certain requests. A local attacker with the CAP_NET_ADMIN could use this to cause a denial of service (system crash).

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. CPU hardware utilizing speculative execution may be vulnerable to cache timing 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; Intel Xeon CPU E5-1650 v3, v2, v4 versions; Xeon E3-1265l v2, v3, v4 Version; Xeon E3-1245 v2, v3, v5, v6 versions; Xeon X7542, etc. Relevant releases/architectures: Image Updates for RHV-H - noarch 3.

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 initial mitigations for IBM Power (PowerPC) and IBM zSeries (S390) architectures are provided. * 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. This fix specifically addresses S390 processors. (CVE-2017-5715, Important) * 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. This fix specifically addresses S390 and PowerPC processors. (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. Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. This fix specifically addresses PowerPC processors. (CVE-2017-5754, Important) Red Hat would like to thank Google Project Zero for reporting CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754.

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

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. Please refer to References section for further information about this issue, CPU microcode requirements and the potential performance impact. 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. (BZ#1549731) * Intel Core X-Series (Skylake) processors use a hardcoded Time Stamp Counter (TSC) frequency of 25 MHz. In some cases this can be imprecise and lead to timing-related problems such as time drift, timers being triggered early, or TSC clock instability. This update mitigates these problems by no longer using the "native_calibrate_tsc()" function to define the TSC frequency. Refined calibration is now used to update the clock rate accordingly in these cases. (BZ#1547854) 4. 7) - noarch, x86_64 3.

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.

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.
