A vulnerability in the way Mozilla products and derivative programs handle certain HTML tags could allow a remote attacker to execute arbitrary code on a vulnerable system.
A vulnerability has been discovered in the way that Mozilla and derived programs handle certain HTML tags. Mozilla Foundation Secuity Advisory 2006-18 states the following:
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 arbitrary 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.
A remote attacker may be able to crash a vulnerable program or run code of their choosing on an affected system. The attacker-supplied code would be executed with the permissions of the user running the vulnerable program.
Thanks to Mozilla Foundation Security Advisory for reporting this vulnerability. The Mozilla Foundation, in turn, credits an anonymous researcher via TippingPoint and the Zero Day Initiative
