HTTP: Apple QuickTime Image Description Atom Sign Extension Memory Corruption
This signature detects attempts to exploit a known vulnerability in Apple QuickTime. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the current user.
Extended Description
Apple QuickTime is prone to a vulnerability that occurs because the bit width of a number is increased without changing its sign in certain image description atoms. A remote attacker can exploit this issue by enticing an unsuspecting user to open a specially crafted Apple video file. Successful exploits will allow the attacker to execute arbitrary code in the context of the user running the application. Failed exploit attempts likely result in denial-of-service conditions. This issue affects Apple QuickTime running on Microsoft Windows Vista, Windows XP SP3, and Mac OS X.
