-- 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 open a malicious file.

The specific flaw exists due to a workaround that was implemented in
order to support recursive cloning of attribute nodes. If an event is
added to the first attribute node, the application can be made to free
the node, and then later access a reference to it. 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
