3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Multiple flaws were found in the location object implementation in
Thunderbird. Malicious content could be used to perform cross-site
scripting attacks, bypass the same-origin policy, or cause Thunderbird to
execute arbitrary code. (CVE-2012-4194, CVE-2012-4195, CVE-2012-4196)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Mariusz Mlynski, moz_bug_r_a4, and Antoine
Delignat-Lavaud as the original reporters of these issues.

Note: None of the issues in this advisory can 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 10.0.10 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
use the Red Hat Network to apply this update are available at
