Dist Redhat Esm H88
Significant spice-gtk enhancement for Red Hat Enterprise Linux resolves major security vulnerability and recommends updating packages.
Updated spice-gtk packages that fix one security issue are now available for Red Hat Enterprise Linux 6

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/site/articles/11258

Summary

The spice-gtk packages provide a GIMP Toolkit (GTK+) widget for SPICE (Simple Protocol for Independent Computing Environments) clients. Both Virtual Machine Manager and Virtual Machine Viewer can make use of this widget to access virtual machines using the SPICE protocol.
spice-gtk communicated with PolicyKit for authorization via an API that is vulnerable to a race condition. This could lead to intended PolicyKit authorizations being bypassed. This update modifies spice-gtk to communicate with PolicyKit via a different API that is not vulnerable to the race condition. (CVE-2013-4324)
All users of spice-gtk are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
