3. Description:

Vino is a Virtual Network Computing (VNC) server for GNOME. It allows
remote users to connect to a running GNOME session using VNC.

A denial of service flaw was found in the way Vino handled certain
authenticated requests from clients that were in the deferred state. A
remote attacker could use this flaw to make the vino-server process enter
an infinite loop when processing those incoming requests. (CVE-2013-5745)

All vino users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. The GNOME session must be
restarted (log out, then log back in) for this update to take effect.

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
https://access.redhat.com/site/articles/11258
