Summary
Red Hat Security Advisory: qemu-kvm security update
Notes
Topic
An update for qemu-kvm is now available for Red Hat Enterprise Linux 7.6 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.
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: 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.
