|
|
This 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 module has been tested successfully on
|
|
Windows 7 SP1.
