Description
Mozilla Firefox 1.5.x before 1.5.0.12 and 2.x before 2.0.0.4, and SeaMonkey 1.0.9 and 1.1.2, allows remote attackers to cause a denial of service via (1) a large cookie path parameter, which triggers memory consumption, or (2) an internal delimiter within cookie path or name values, which could trigger a misinterpretation of cookie data, aka "Path Abuse in Cookies."
