Test ID:1.3.6.1.4.1.25623.1.0.870706
Category:Red Hat Local Security Checks
Title:RedHat Update for qemu-kvm RHSA-2011:0345-01
Summary:The remote host is missing an update for the 'qemu-kvm'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'qemu-kvm'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
qemu-kvm on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
