Description

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML content.
Malicious HTML content could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-2982)

A dangling pointer flaw was found in the Thunderbird Scalable Vector
Graphics (SVG) text manipulation routine. An HTML mail message containing a
malicious SVG image could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-0084)

A dangling pointer flaw was found in the way Thunderbird handled a certain
Document Object Model (DOM) element. An HTML mail message containing
malicious content could cause Thunderbird to crash or, potentially, execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-2378)

All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.
