TITLE:
Mozilla Firefox XSLT Processing Invalid Evaluation Context Weakness

SECUNIA ADVISORY ID:
SA34471

VERIFY ADVISORY:
http://secunia.com/advisories/34471/

DESCRIPTION:
A weakness has been discovered in Mozilla Firefox, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The weakness is caused due to the improper handling of errors
encountered when transforming an XML document. This can be exploited
to trigger the handling of a temporary, corrupted stack variable as
an evaluation context object via specially crafted XSLT code.

Successful exploitation crashes the browser. However, even though
code execution has not been proven, it cannot be completely ruled
out.

NOTE: Secunia normally does not classify a browser crash as a
vulnerability nor issue an advisory about it. However, the potential
impact of this issue may be more severe than currently believed.

The weakness is confirmed in version 3.0.7 for Windows. Other
versions may also be affected.

SOLUTION:
Do not browse untrusted websites or follow untrusted links.
