Topic

An update for qemu-kvm-rhev is now available for Red Hat Enterprise Linux
OpenStack Platform 7.0 (Kilo) for RHEL 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.

Description

KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the
user-space component for running virtual machines using KVM in environments
managed by Red Hat Enterprise Virtualization Manager.

Security Fix:

  • An out-of-bounds read/write access flaw was found in the way QEMU's VGA

emulation with VESA BIOS Extensions (VBE) support performed read/write
operations using I/O port methods. A privileged guest user could use
this flaw to execute arbitrary code on the host with the privileges of the
host's QEMU process. (CVE-2016-3710)

Red Hat would like to thank Wei Xiao (360 Marvel Team) and Qinghao Tang
(360 Marvel Team) for reporting this issue.
