RHSA-2013:0169 - Security Advisory

Synopsis

Moderate: vino security update

Type/Severity

Security Advisory: Moderate

Topic

An updated vino package that fixes several security issues is now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

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

It was found that Vino transmitted all clipboard activity on the system
running Vino to all clients connected to port 5900, even those who had not
authenticated. A remote attacker who is able to access port 5900 on a
system running Vino could use this flaw to read clipboard data without
authenticating. (CVE-2012-4429)

Two out-of-bounds memory read flaws were found in the way Vino processed
client framebuffer requests in certain encodings. An authenticated client
could use these flaws to send a specially-crafted request to Vino, causing
it to crash. (CVE-2011-0904, CVE-2011-0905)

In certain circumstances, the vino-preferences dialog box incorrectly
indicated that Vino was only accessible from the local network. This could
confuse a user into believing connections from external networks are not
allowed (even when they are allowed). With this update, vino-preferences no
longer displays connectivity and reachable information. (CVE-2011-1164)

There was no warning that Universal Plug and Play (UPnP) was used to open
ports on a user's network router when the "Configure network automatically
to accept connections" option was enabled (it is disabled by default) in
the Vino preferences. This update changes the option's description to avoid
the risk of a UPnP router configuration change without the user's consent.
(CVE-2011-1165)

All Vino users should upgrade to this updated package, which contains
backported patches to resolve these issues. The GNOME session must be
restarted (log out, then log back in) for this update to take effect.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
