-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Mozilla Firefox. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or otherwise render a malicious file.

The specific flaw exists within a particular XSLT transformation when
applied to an XML document. If a large number of elements have this
transformation applied to them, the application will misallocate a
buffer. Upon usage of this buffer the application will copy more data
than allocated thus causing an overflow. This can lead to code execution
under the context of the application.

-- Vendor Response:
Mozilla Firefox has issued an update to correct this vulnerability. More
