Mozilla @ Prone again!!!!

1.    Mozilla Firefox 3.5.x through 3.5.14 and 3.6.x through 3.6.11, when JavaScript is enabled, allows remote attackers to execute arbitrary code via vectors related to nsCSSFrameConstructor::ContentAppended, the appendChild method, incorrect index tracking, and the creation of multiple frames, which triggers memory corruption, as exploited in the wild in October 2010 by the Belmoo malware.
