-- 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 in js3250.dll. When a JavaObject is created and
deleted, there is not a proper sanity check for the
LookupGetterorSetter() function, which can result in a dangling pointer
being passed to the JS_ValueToId() function. A remote attacker can
exploit this vulnerability to execute arbitrary code under the context
of the SYSTEM user.

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