Description: The libvirt library contains a C API for managing and interacting with the virtualizationcapabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. 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-2018-12127) * Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11091) For more details about the security issue(s), includingthe impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. 4.

security advisoryRed HatcriticalRed Hat 6.7 RHSA-2018-1826-01 Critical: Kernel Speculative Execution
An update for kernel is now available for Red Hat Enterprise Linux 6.7 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security, bug fix, and enhancement update Advisory ID: RHSA-2018:1826-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:1826 Issue date: 2018-06-12 CVE Names: CVE-2018-3639 ==================================================================== 1. Summary: An update for kernel is now available for Red Hat Enterprise Linux 6.7 Extended Update Support. 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 HPC Node EUS (v. 6.7) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - x86_64 Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.7) - i386, ppc64, s390x, x86_64 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 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 intothe 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, PowerPC) Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting this issue. Bug Fix(es) and Enhancement(s): These updated kernel packages include also numerous bug fixes and enhancements. Space precludes documenting all of the bug fixes and enhancements in this advisory. See the descriptions in the related Knowledge Article: https://access.redhat.com/articles/3483021 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.

Synopsis: Important: kernel security update Advisory ID: SLSA-2018:0007-1 Issue Date: 2018-01-03 CVE Numbers: CVE-2017-5753 CVE-2017-5715 CVE-2017-5754 -- 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. The performance impact of these patches may vary considerably based on workload and hardware configuration. 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 aprecisely-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. -- SL7 x86_64 kernel-3.10.0-693.11.6.el7.x86_64.rpm kernel-debug-3.10.0-693.11.6.el7.x86_64.rpm kernel-debug-debuginfo-3.10.0-693.11.6.el7.x86_64.rpm kernel-debug-devel-3.10.0-693.11.6.el7.x86_64.rpm kernel-debuginfo-3.10.0-693.11.6.el7.x86_64.rpm kernel-debuginfo-common-x86_64-3.10.0-693.11.6.el7.x86_64.rpm kernel-devel-3.10.0-693.11.6.el7.x86_64.rpm kernel-headers-3.10.0-693.11.6.el7.x86_64.rpm kernel-tools-3.10.0-693.11.6.el7.x86_64.rpm kernel-tools-debuginfo-3.10.0-693.11.6.el7.x86_64.rpm kernel-tools-libs-3.10.0-693.11.6.el7.x86_64.rpm perf-3.10.0-693.11.6.el7.x86_64.rpm perf-debuginfo-3.10.0-693.11.6.el7.x86_64.rpm python-perf-3.10.0-693.11.6.el7.x86_64.rpm python-perf-debuginfo-3.10.0-693.11.6.el7.x86_64.rpm kernel-tools-libs-devel-3.10.0-693.11.6.el7.x86_64.rpm noarch kernel-abi-whitelists-3.10.0-693.11.6.el7.noarch.rpm kernel-doc-3.10.0-693.11.6.el7.noarch.rpm - Scientific Linux Development Team .
