1. Summary:

An updated qspice-client package that fixes one security issue is 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.

2. Relevant releases/architectures:

RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The Simple Protocol for Independent Computing Environments (SPICE) is a
remote display protocol used in Red Hat Enterprise Linux for viewing
virtualized guests running on the Kernel-based Virtual Machine (KVM)
hypervisor, or on Red Hat Enterprise Virtualization Hypervisor.

The qspice-client package provides the client side of the SPICE protocol.

A race condition was found in the way the SPICE Mozilla Firefox plug-in and
the SPICE client communicated. A local attacker could use this flaw to
trick the plug-in and the SPICE client into communicating over an
attacker-controlled socket, possibly gaining access to authentication
details, or resulting in a man-in-the-middle attack on the SPICE
connection. (CVE-2010-2792)

Users of qspice-client should upgrade to this updated package, which
contains a backported patch to correct this issue.

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
