Summary

The LookupGetterOrSetter function in js3250.dll in Mozilla Firefox before 3.5.14 and 3.6.x before 3.6.11, Thunderbird before 3.0.9 and 3.1.x before 3.1.5, and SeaMonkey before 2.0.9 does not properly support window.__lookupGetter__ function calls that lack arguments, which allows remote attackers to execute arbitrary code or cause a denial of service (incorrect pointer dereference and application crash) via vectors involving a "dangling pointer" and the JS_ValueToId function.
