Mozilla Thunderbird is the next-generation mail client from the
Mozilla project.
The following vulnerabilities were found and fixed in Mozilla
<li>"moz_bug_r_a4" and "shutdown" discovered
that Thunderbird was improperly cloning base objects (MFSA
<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
<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
<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>
<impact type="normal">
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.
There are no known workarounds for all the issues at this time.
All Mozilla Thunderbird users should upgrade to the latest
# emerge --sync
