This module exploits a stack based buffer overflow in CCMPlayer 1.5. Opening
a m3u playlist with a long track name, a SEH exception record can be overwritten
with parts of the controllable buffer. SEH execution is triggered after an
invalid read of an injectible address, thus allowing arbitrary code execution.
This module works on multiple Windows platforms including: Windows XP SP3,
Windows Vista, and Windows 7.
