Mozilla Firefox Tag Order Vulnerability
A particular sequence of HTML tags that reliably crash Mozilla clients was
reported by an anonymous researcher via TippingPoint and the Zero Day
Initiative. The crash is due to memory corruption that can be exploited to
run arbitary code.
Mozilla mail clients will crash on the tag sequence, but without the ability
to run scripts to fill memory with the attack code it may not be possible
for an attacker to exploit this crash.
Upgrade to a fixed version.
This issue also affects FC4
