Loading vulnerability…
An integer signedness error in Apple QuickTime prior to version 7.7 allows remote attackers to execute arbitrary code or cause a denial of service by supplying a crafted PICT file containing a malicious PnSize opcode. The flaw leads to a stack-based buffer overflow due to improper handling of integer values, resulting in memory corruption.

This repository contains a single Metasploit module (apple_quicktime_pnsize.rb) that exploits a buffer overflow vulnerability (CVE-2011-0257) in Apple QuickTime Player 7.60.92.0 on Windows XP SP3. The exploit works by generating a malicious .mov file with a specially crafted PnSize value, which, when opened by the target, triggers a buffer overflow and allows arbitrary code execution. The module includes a ROP chain to bypass DEP and supports customizable payloads via Metasploit. The main attack vector is local, requiring the victim to open the malicious file. The repository references the PICT file format specification and provides default filenames for the generated exploit file. The code is operational and suitable for use in penetration testing or red teaming scenarios targeting the specified QuickTime version.
