New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

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

Update the affected vino and / or vino-debuginfo packages.
