An Unsafe Search Path vulnerability in FortiClient Online Installer (Windows version before 6.0.6) may allow an unauthenticated, remote attacker with control over the directory in which FortiClientOnlineInstaller.exe resides to execute arbitrary code on the system via uploading malicious .dll files in that directory. FortiClient Online Installer Contains an unreliable search path vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Fortinet FortiClient is prone to a arbitrary code-execution vulnerability. A remote attacker can leverage this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in a denial of service condition. Versions prior to FortiClient 6.0.6 are vulnerable. Fortinet FortiClient is a mobile terminal security solution developed by Fortinet. The solution provides IPsec and SSL encryption, WAN optimization, endpoint compliance, and two-factor authentication when connected to FortiGate firewall appliances. FortiClient Online Installer is an online installer for FortiClient. A code issue vulnerability exists in the FortiClient Online Installer in Fortinet FortiClient versions prior to 6.0.6 (Windows). This vulnerability stems from improper design or implementation problems in the code development process of network systems or products

Summary: An update for qemu-kvm-rhev is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7 and Red Hat Virtualization Engine 4.3. 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. Relevant releases/architectures: RHV-M 4.3 - x86_64 Red Hat Virtualization 4 Management Agent for RHEL 7 Hosts - ppc64le, x86_64 3. Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. Security Fix(es): * A flaw was found in the implementation of the "fill buffer", a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130) * Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126) * Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel. (CVE-2019-11091) * QEMU: device_tree: heap buffer overflow while loading device tree blob (CVE-2018-20815) * QEMU: rtl8139: integer overflow leads to buffer overflow (CVE-2018-17958) * QEMU: net: ignore packets with large size (CVE-2018-17963) * QEMU: scsi-generic: possible OOB access while handling inquiry request (CVE-2019-6501) * QEMU: slirp: information leakage in tcp_emu() due to uninitialized stack variables (CVE-2019-9824) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE Name: CVE-2019-11135, CVE-2019-11139, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2018-11091, CVE-2017-5715 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/>. I. Background - From time to time Intel releases new CPU microcode to address functional issues and security vulnerabilities. Such a release is also known as a Micro Code Update (MCU), and is a component of a broader Intel Platform Update (IPU). FreeBSD distributes CPU microcode via the devcpu-data port and package. II. Problem Description Starting with version 1.26, the devcpu-data port/package includes updates and mitigations for the following technical and security advisories (depending on CPU model). Intel TSX Updates (TAA) CVE-2019-11135 Voltage Modulation Vulnerability CVE-2019-11139 MD_CLEAR Operations CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2018-11091 TA Indirect Sharing CVE-2017-5715 EGETKEY CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2018-11091 JCC SKX102 Erratum Updated microcode includes mitigations for CPU issues, but may also cause a performance regression due to the JCC erratum mitigation. Please visit http://www.intel.com/benchmarks for further information. Please visit http://www.intel.com/security for detailed information on these advisories as well as a list of CPUs that are affected. III. Impact Operating a CPU without the latest microcode may result in erratic or unpredictable behavior, including system crashes and lock ups. Certain issues listed in this advisory may result in the leakage of privileged system information to unprivileged users. Please refer to the security advisories listed above for detailed information. IV. Workaround To determine if TSX is present in your system, run the following: 1. kldload cpuctl 2. cpucontrol -i 7 /dev/cpuctl0 If bits 4 (0x10) and 11 (0x800) are set in the second response word (EBX), TSX is present. In the absence of updated microcode, TAA can be mitigated by enabling the MDS mitigation: 3. sysctl hw.mds_disable=1 Systems must be running FreeBSD 11.3, FreeBSD 12.1, or later for this to work. *IMPORTANT* If your use case can tolerate leaving the CPU issues unmitigated and cannot tolerate a performance regression, ensure that the devcpu-data package is not installed or is locked at 1.25 or earlier. # pkg delete devcpu-data or # pkg lock devcpu-data Later versions of the LLVM and GCC compilers will include changes that partially relieve the peformance impact. V. Solution Install the latest Intel Microcode Update via the devcpu-data port/package, version 1.26 or later. Updated microcode adds the ability to disable TSX. With updated microcode the issue can still be mitigated by enabling the MDS mitigation as described in the workaround section, or by disabling TSX instead: 1. kldload cpuctl 2. cpucontrol -i 7 /dev/cpuctl0 If bit 29 (0x20000000) is set in the fourth response word (EDX), then the 0x10a MSR is present. 3. cpucontrol -m 0x10a /dev/cpuctl0 If bit 8 (0x100) of the response word is set, your CPU is not vulnerable to TAA and no further action is required. If bit 7 (0x80) is cleared, then your CPU does not have updated microcode that facilitates TSX to be disabled. The only remedy available is to enable the MDS mitigation, as documented above. 4. cpucontrol -m 0x122=3 /dev/cpuctl0 Repeat step 4 for each numbered CPU that is present. A future kernel change to FreeBSD will provide automatic detection and mitigation for TAA. LLVM 9.0 will be updated in FreeBSD 13-current to address the JCC peformance impact. Updates to prior versions of LLVM are currently being evaluated. VI. Correction details There are currently no changes in FreeBSD to address this issue. VII.
