Signature Detail

HTTP: Apple QuickTime PICT Poly Underflow

This signature detects attempts to exploit a known vulnerability in Apple QuickTime multimedia player. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the user.

Extended Description

Apple QuickTime is prone to multiple heap-based buffer-overflow vulnerabilities because it fails to perform adequate boundary checks on user-supplied data. An attacker can exploit these issues by enticing an unsuspecting user to open a specially crafted PICT image file. Successfully exploiting these issues allows remote attackers to execute arbitrary code in the context of the user running the application. Failed exploit attempts likely result in denial-of-service conditions. These issues affects Apple QuickTime running on Microsoft Windows Vista, Microsoft Windows XP SP2, and Mac OS X.
