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.
