The JavaScript engine in Mozilla Firefox before 3.0.7 Thunderbird before 2.0.0.21 and SeaMonkey 1.1.15 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a splice of an array that contains "some non-set elements" which causes jsarray.cpp to pass an incorrect argument to the ResizeSlots function which triggers memory corruption; (2) vectors related to js_DecompileValueGenerator jsopcode.cpp __defineSetter__ and watch which triggers an assertion failure or a segmentation fault; and (3) vectors related to gczeal __defineSetter__ and watch which triggers a hang.
