Synopsis

Several vulnerabilities in Mozilla Thunderbird allow attacks ranging from execution of script code with elevated privileges to information leak.

2. Impact Information

Background

Mozilla Thunderbird is the next-generation mail client from the Mozilla project.

Description

The following vulnerabilities were found and fixed in Mozilla Thunderbird:

"moz_bug_r_a4" and "shutdown" discovered that Thunderbird was improperly cloning base objects (MFSA 2005-56).
"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).
"shutdown" discovered a possibly exploitable crash in InstallVersion.compareTo (MFSA 2005-50).
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).
Georgi Guninski reported missing Install object instance checks in the native implementations of XPInstall-related JavaScript objects (MFSA 2005-40).
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).

Impact

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.

3. Resolution Information

Workaround

There are no known workarounds for all the issues at this time.
