# Exploit Title: VideoSpirit Pro v1.68 Local BoF Exploit
# Date: 01/08/2011
# Author: xsploitedsec
# URL: http://www.x-sploited.com/
# Contact: xsploitedsec[at]x-sploited.com
# Software Link: http://www.verytools.com/videospirit/download.html
# Vulnerable version: v1.68
# Tested on: Windows XP SP3 Eng

# Software description #
# "VideoSpirit Pro is the most easily used Video Converter/Editor tools. For acting as a Video Editor,
# various slide effect/title/subtitle can be added to a video clip. Also, the video clip can be rotated,
# resized and warped. Multiple video/audio clips can be joined together. Converting speed is fast and
# the quality of output file is excellent."

# Vulnerability info #
# VideoSpirit Pro is prone to a buffer overflow when parsing a (.visprj) project file that
# contains an overly long "mp3" value. This is because the application fails to properly bounds
# check the data before it is passed to strcpy().
