Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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

Red Hat Product Security 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. The qemu-kvm-rhev package
provides the user-space component for running virtual machines using
KVM.

A heap buffer overflow flaw was found in the way QEMU's NE2000 NIC
emulation implementation handled certain packets received over the
network. A privileged user inside a guest could use this flaw to crash
the QEMU instance (denial of service) or potentially execute arbitrary
code on the host. (CVE-2015-5279)

Red Hat would like to thank Qinghao Tang of QIHU 360 Inc. for
reporting this issue.

All qemu-kvm-rhev users are advised to upgrade to these updated
packages, which contain a backported patch 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.
