Background

Mozilla Thunderbird is a popular open-source email client from the Mozilla project.

Description

Multiple vulnerabilities have been reported in Mozilla Thunderbird's HTML browser engine (CVE-2007-5339) and JavaScript engine (CVE-2007-5340) that can be exploited to cause a memory corruption.

Impact

A remote attacker could entice a user to read a specially crafted email that could trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code.

Workaround

There is no known workaround at this time for all of these issues, but some of them can be avoided by disabling JavaScript.

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-2.0.0.9"
