/*
========================================================================
0-day BlazeVideo HDTV Player <= v2.1 Malformed PLF Buffer Overflow PoC
========================================================================
BlazeVideo HDTV v2.1 and prior fails to properly handle large file paths inside
PLF files, the result is a stack based buffer overflow that allows an
attacker to execute code in the context of the player.

This exploit should also work for BlazeDVD v5.0, but i havent gotten
around to testing it.

C: + [BUFFER x 257 bytes] + [JMP] + [16 Garbage bytes] + [SHELLCODE in ESP]


Happy Hunting and Happy Holidays to everyone
