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.
Resolution
==========
All Mozilla Thunderbird users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
