Summary
Red Hat Security Advisory: qemu-kvm security and bug fix 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 Moderate. 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):
* QEMU: loader: OOB access while loading registered ROM may lead to code execution (CVE-2020-13765)
* QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c (CVE-2020-16092)
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):
* qemu-kvm FTBFS on rhel7.9 (BZ#1884997)
