Description


Updated qemu-kvm packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component
for running virtual machines using KVM.

An unquoted search path flaw was found in the way the QEMU Guest Agent
service installation was performed on Windows. Depending on the permissions
of the directories in the unquoted search path, a local, unprivileged user
could use this flaw to have a binary of their choosing executed with SYSTEM
privileges. (CVE-2013-2231)

This issue was discovered by Lev Veyde of Red Hat.

All users of qemu-kvm should upgrade to these updated packages, which
contain backported patches to correct this issue. After installing this
update, shut down all running virtual machines. Once all virtual machines
have shut down, start them again for this update to take effect.
