Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2013:1452 :

Updated vino packages that fix one security issue are now available
for Red Hat Enterprise Linux 5 and 6.

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.

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.
