CVEs (cve.mitre.org): CVE-2011-0011

Details

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.

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.


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
