Summary

Red Hat Security Advisory: qemu-kvm security, bug fix, and enhancement update

Notes

Topic

An update for qemu-kvm is now available for Red Hat Enterprise Linux 7. 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.

Details

Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM. Security Fix(es): * hw: TSX Transaction Asynchronous Abort (TAA) (CVE-2019-11135) * QEMU: slirp: heap buffer overflow during packet reassembly (CVE-2019-14378) 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. Bug Fix(es): * [Intel 7.8 Bug] [KVM][CLX] CPUID_7_0_EDX_ARCH_CAPABILITIES is not enabled in VM qemu-kvm (BZ#1730606) Enhancement(s): * [Intel 7.8 FEAT] MDS_NO exposure to guest - qemu-kvm (BZ#1755333)

A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing.\r\n\r\nIntel\u0027s Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections. The CPU executes instructions in the critical-sections as transactions, while ensuring their atomic state. When such transaction execution is unsuccessful, the processor cannot ensure atomic updates to the transaction memory, so the processor rolls back or aborts such transaction execution.\r\n\r\nWhile TSX Asynchronous Abort (TAA) is pending, CPU may continue to read data from architectural buffers and pass it to the dependent speculative operations. This may cause information leakage via speculative side-channel means, which is quite similar to the Microarchitectural Data Sampling (MDS) issue.",
