Red Hat Security Advisory

 

Synopsis: Moderate: qemu-kvm security update

Advisory ID: RHSA-2011:0345-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0345.html

=====================================================================

 

1. Summary:

 

Updated qemu-kvm 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 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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - x86_64

Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

Red Hat Enterprise Linux Server (v. 6) - x86_64

Red Hat Enterprise Linux Workstation (v. 6) - x86_64

 

3. Description:

 

KVM (Kernel-based Virtual Machine) is a full virtualization solution for

Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component

for running virtual machines using KVM. Virtual Network Computing (VNC) is

a remote display system.

 

A flaw was found in the way the VNC "password" option was handled. Clearing

a password disabled VNC authentication, allowing a remote user able to

connect to the virtual machines' VNC ports to open a VNC session without

authentication. (CVE-2011-0011)

 

All users of qemu-kvm should upgrade to these updated packages, which

contain a backported patch to resolve 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.

 

4. 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
