Red Hat Product Errata RHSA-2012:0149 - Security Advisory
Issued:
2012-02-21
Updated:
2012-02-21

RHSA-2012:0149 - Security Advisory

  • Overview
  • Updated Packages

Synopsis

Moderate: kvm security and bug fix update

Type/Severity

Security Advisory: Moderate

Topic

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

The Red Hat Security Response Team has rated this update as having moderate
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.

Description

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.

It was found that the kvm_vm_ioctl_assign_device() function in the KVM
subsystem of a Linux kernel did not check if the user requesting device
assignment was privileged or not. A member of the kvm group on the host
could assign unused PCI devices, or even devices that were in use and
whose resources were not properly claimed by the respective drivers, which
could result in the host crashing. (CVE-2011-4347)

Red Hat would like to thank Sasha Levin for reporting this issue.

These updated kvm packages include several bug fixes. Space precludes
documenting all of these changes in this advisory. Users are directed to
the Red Hat Enterprise Linux 5.8 Technical Notes, linked to in the
References, for information on the most significant of these changes.

All KVM users should upgrade to these updated packages, which contain
backported patches to correct these issues. Note: 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/kb/docs/DOC-11259

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.
