|Description||Mozilla Firefox before 22.214.171.124 and 3.x before 3.0.1, Thunderbird before 126.96.36.199, 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.|
