Greetings,
  There is a DOS condition on windows media player when the klite codec pack
is installed.

# Exploit Title: Windows Media Player with klite codec pack DOS Poc
# Date: 14/06/2011
# Author: Nicolas Krassas , www.twitter.com/dinosn
# Version:Windows Media Player 12
# Tested on: Windows 7

The 3gp handling from MP4Splitter.ax filter of klite codec pack will cause
an Access violation when a specially crafted movie file is loaded on the
media player. The same crash will occur also when the file is loaded on a
playlist and the media player will try to generate thumbnail image of the
contents.
