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 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. The qemu-kvm-rhev packages
form the user-space component for running virtual machines using KVM.

A flaw was found in the way QEMU-KVM emulated the e1000 network
interface card when the host was configured to accept jumbo network
frames, and a guest using the e1000 emulated driver was not. A remote
attacker could use this flaw to crash the guest or, potentially,
execute arbitrary code with root privileges in the guest.
(CVE-2012-6075)

All users of qemu-kvm-rhev are advised to upgrade to these updated
packages, which 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.
