DESCRIPTION:
Multiple vulnerabilities have been reported in Mozilla Firefox and
Thunderbird, which can be exploited by malicious people to bypass
certain security restrictions and compromise a user's system.

For more information:
SA44972

1) Some unspecified errors can be exploited to corrupt memory. No
further information is currently available.

This vulnerability affects Firefox 3.6.x only.

2) A use-after-free error in the "nsSVGPathSegList::ReplaceItem()"
method when processing SVG element lists can be exploited to access
an invalid element list when a user supplied callback deletes an
object.

3) A use-after-free error in the "nsSVGPointList::AppendElement()"
method when processing SVG element lists can be exploited to access
an invalid element list when a user supplied callback deletes an
object.

4) A use-after-free error in "nsXULCommandDispatcher" when processing
XUL documents can be exploited to remove the currently used command
updater.

Successful exploitation of vulnerabilities #1 - #4 may allow
execution of arbitrary code.

5) An error when handling cookies for two domains where one contains
a trailing dot character can be exploited to bypass the same-origin
policy and disclose a cookie to a third party.

The vulnerabilities are reported in the following products:
* Firefox versions prior to 3.6.18.
* Thunderbird versions prior to 3.1.11.

SOLUTION:
Update to Firefox version 3.6.18 and Thunderbird version 3.1.11.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits the following people:
1) Luke Wagner and Gary Kwong.
2 - 4) regenrecht via ZDI.
5) David Chan, Mozilla Security Researcher.
