Description
Stack-based buffer overflow in Mozilla Firefox allows remote attackers to execute arbitrary code via unspecified vectors involving JavaScript. NOTE: the vendor and original researchers have released a follow-up comment disputing the severity of this issue, in which the researcher states that "we mentioned that there was a previously known Firefox vulnerability that could result in a stack overflow ending up in remote code execution. However, the code we presented did not in fact do this... I have not succeeded in making this code do anything more than cause a crash and eat up system resources"
