3. Description:

 

Mozilla Thunderbird is a standalone mail and newsgroup client.

 

A flaw was found in the way Thunderbird handled frame objects with certain

names. An attacker could use this flaw to cause a plug-in to grant its

content access to another site or the local file system, violating the

same-origin policy. (CVE-2011-2999)

 

An integer underflow flaw was found in the way Thunderbird handled large

JavaScript regular expressions. An HTML mail message containing malicious

JavaScript could cause Thunderbird to access already freed memory, causing

Thunderbird to crash or, potentially, execute arbitrary code with the

privileges of the user running Thunderbird. (CVE-2011-2998)

 

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.
