<p>
Mozilla Thunderbird is the next-generation mail client from the
Mozilla project.
</p>
</background>
<description>
<p>
The following vulnerabilities were found and fixed in Mozilla
Thunderbird:
</p>
<ul>
<li>"moz_bug_r_a4" and "shutdown" discovered
that Thunderbird was improperly cloning base objects (MFSA
2005-56).</li>
<li>"moz_bug_r_a4" also reported that Thunderbird was
overly trusting contents, allowing privilege escalation via property
overrides (MFSA 2005-41, 2005-44), that it failed to validate XHTML DOM
nodes properly (MFSA 2005-55), and that XBL scripts ran even when
Javascript is disabled (MFSA 2005-46).</li>
<li>"shutdown" discovered a
possibly exploitable crash in InstallVersion.compareTo (MFSA
2005-50).</li>
<li>Andreas Sandblad from Secunia reported that a child
frame can call top.focus() even if the framing page comes from a
different origin and has overridden the focus() routine (MFSA
2005-52).</li>
<li>Georgi Guninski reported missing Install object
instance checks in the native implementations of XPInstall-related
JavaScript objects (MFSA 2005-40).</li>
<li>Finally, Vladimir V.
Perepelitsa discovered a memory disclosure bug in JavaScript's regular
expression string replacement when using an anonymous function as the
replacement argument (CAN-2005-0989 and MFSA 2005-33).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could craft malicious email messages that would
leverage these issues to inject and execute arbitrary script code with
elevated privileges or help in stealing information.
</p>
</impact>
<workaround>
<p>
There are no known workarounds for all the issues at this time.
</p>
</workaround>
<resolution>
<p>
All Mozilla Thunderbird users should upgrade to the latest
version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.0.5"</code>
<p>
All Mozilla Thunderbird binary users should upgrade to the
latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.0.5"</code>
</resolution>
