受影响系统：
un4seen XMPlayer 3.3.0.4描述：
BUGTRAQ ID: 21206
XMPlay是一款免费、强大的Windows音乐播放器。
XMPlay在解析包含有超长文件名（大于500字节）的M3U播放列表时存在栈溢出漏洞，远程攻击者可能利用此漏洞在用户机器上执行任意指令。
如果攻击者受骗加载了恶意的M3U文件时就会触发这个漏洞，导致执行任意代码。

===================================================================
0-day XMPlay 3.3.0.4 .M3U Filename Buffer Overflow Exploit
===================================================================
XMPlay 3.3.0.4 and lower experiance a stack-based buffer overflow when
loading malformed M3U files (probably PLS and ASX files as well).
This merely executes CALC.exe but you could always add your own custom
shellcode (alpha2)
Either the DisplayName field of the M3U or the FileName field can be
used to exploit the system, but during my tests, using the DisplayName
field caused Windows DEP to activate. (English Windows XP SP2)
Huge Greets and Thanks to Expanders (expanders[at]gmail[dot]com)
Who I presented the PoC and Discovery to, and he wrote the first PoC
Exploit for it. And Jerome Athias for some neat tools. Both of these
guys are very talented, keep up the good work.
Someone should try this with ASX and PLS files, i bet it works as well.
