Synopsis
========

Multiple vulnerabilities have been reported in Mozilla Thunderbird,
which may allow user-assisted arbitrary remote code execution.

Background
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package                  /  Vulnerable  /              Unaffected
    -------------------------------------------------------------------
  1  mozilla-thunderbird          < 2.0.0.9                 >= 2.0.0.9
  2  mozilla-thunderbird-bin      < 2.0.0.9                 >= 2.0.0.9
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

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
">=mail-client/mozilla-thunderbird-2.0.0.9"

All Mozilla Thunderbird binary users should upgrade to the latest
version:

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