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

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

2) An error in the WebGLES library when loading a shader can be
exploited to cause a buffer overflow and execute arbitrary code.

3) An off-by-three error in libGLESv2 can be exploited to corrupt
memory and execute arbitrary code.

NOTE: Additionally, a weakness exists within the "generate-id()"
XPath function (libxslt), which can be exploited to disclose certain
addresses from the heap.

The vulnerabilities are reported in versions prior to 4.0.1.

SOLUTION:
Update to version 4.0.1.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits Boris Zbarsky, Gary Kwong, Jesse Ruderman,
Michael Wu, Nils, Scoobidiver, Ted Mielczarek, Alcidion, and Ian
Beer.
2) Christoph Diehlm, Mozilla.
3) Yuri Ko.
