CVEs (cve.mitre.org): CVE-2012-6075

Details

Updated kvm packages that fix one security issue are now available for Red
Hat Enterprise Linux 5.

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. KVM is a Linux kernel module built for
the standard Red Hat Enterprise Linux kernel.

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 kvm are advised to upgrade to these updated packages, which
contain backported patches to correct this issue. Note that the procedure
in the Solution section must be performed before this update will take
effect.


Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

The following procedure must be performed before this update will take
effect:

1) Stop all KVM guest virtual machines.

2) Either reboot the hypervisor machine or, as the root user, remove (using
"modprobe -r [module]") and reload (using "modprobe [module]") all of the
following modules which are currently running (determined using "lsmod"):
kvm, ksm, kvm-intel or kvm-amd.

3) Restart the KVM guest virtual machines.
