DESCRIPTION:
Multiple vulnerabilities have been reported in Mozilla Firefox and
Mozilla SeaMonkey, which can be exploited by malicious, local users
to gain escalated privileges and by malicious people to disclose
sensitive information and compromise a user's system.

1) Multiple errors in the browser engine can be exploited to corrupt
memory and potentially execute arbitrary code.

2) Multiple use-after-free errors within the handling of the
"mChannel", "mObserverList", and "nsTreeRange" object attributes can
be exploited to execute arbitrary code.

3) An error when handling Java applets can be exploited to steal
entries from the form history via the autocomplete controls.

4) An error within the Java Embedding Plugin (JEP) can be exploited
to gain escalated privileges.

This vulnerability only affects the Mac OS X versions.

5) An error in the implementation of the "resource:" protocol can be
exploited to perform directory traversal attacks and disclose
sensitive information.

This vulnerability only affects the Windows versions.

NOTE: A weakness in libxslt, which could lead to disclosure of heap
addresses has also been reported.

SOLUTION:
Update to Mozilla Firefox version 3.5.19 or 3.6.17 and Mozilla
SeaMonkey version 2.0.14.
