"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.

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."
