Buffer overflow in Firefox 3.0 and 2.0.x has unknown impact and attack vectors. NOTE: due to lack of details as of 20080619, it is not clear whether this is the same issue as CVE-2008-2785. A CVE identifier has been assigned for tracking purposes.

Mozilla Firefox before 2.0.0.16 and 3.x before 3.0.1, Thunderbird before 2.0.0.16, and SeaMonkey before 1.1.11 use an incorrect integer data type as a CSS object reference counter in the CSSValue array (aka nsCSSValue:Array) data structure, which allows remote attackers to execute arbitrary code via a large number of references to a common CSS object, leading to a counter overflow and a free of in-use memory, aka ZDI-CAN-349.
