Just recently, a flaw in Firefox has been announced that could result in the browser crashing. Affecting both the earlier 220.127.116.11 and the newly released Firefox 2.0. This particular flaw is interesting in that it really cannot be verified if the scope of the bug ends at just a crash, those most agree that it does. The bug was reported originally a few months ago, and someadvisories already exist along with notes in Bugzilla. There is a sample snippet of code in Bugzilla, and running it on Firefox on my machine resulted in 2.0 crashing, although the scope of the bug ends there and no other damage could really happen. The articles and NIST advisory do not mention anything else regarding the flaw. It can't lead to system compromise, so it isn't serious in nature as most announced flaws, but is interesting nevertheless.
