3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed content. Malicious
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2013-0788)

A flaw was found in the way Same Origin Wrappers were implemented in
Thunderbird. Malicious content could use this flaw to bypass the
same-origin policy and execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2013-0795)

A flaw was found in the embedded WebGL library in Thunderbird. Malicious
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. Note: This issue
only affected systems using the Intel Mesa graphics drivers.
(CVE-2013-0796)

An out-of-bounds write flaw was found in the embedded Cairo library in
Thunderbird. Malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2013-0800)

A flaw was found in the way Thunderbird handled the JavaScript history
functions. Malicious content could cause a page to be displayed that
has a baseURI pointing to a different site, allowing cross-site scripting
(XSS) and phishing attacks. (CVE-2013-0793)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Olli Pettay, Jesse Ruderman, Boris Zbarsky, Christian
Holler, Milan Sreckovic, Joe Drew, Cody Crews, miaubiz, Abhishek Arya, and
Mariusz Mlynski as the original reporters of these issues.

Note: All issues except CVE-2013-0800 cannot be exploited by a
specially-crafted HTML mail message as JavaScript is disabled by default
for mail messages. They could be exploited another way in Thunderbird, for
example, when viewing the full remote content of an RSS feed.

All Thunderbird users should upgrade to this updated package, which
contains Thunderbird version 17.0.5 ESR, which corrects these issues. After
installing the update, Thunderbird must be restarted for the changes 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
