Hyperdose Security Advisory

Severity: Moderate
Author: Robert Fly - robfly@hyperdose.com

--MusicMatch Description--
From Musicmatch.com, "Musicmatch Jukebox 10 is the most powerful way to find
and organize your music, giving you ultimate control of your music
experience."  In September 04 Musicmatch was purchased by Yahoo! Inc.

--Bug Details--
There are several temp and log files stored by Musicmatch, many of which are
stored under Program Files.  Because log data can contain personal user
information, such as what songs they are listening to, this data should be
stored under the users own profile.  If not users run the risk of
inadvertantly exposing information which they may not want others to access.
One such example of this is the log file stored in "c:\program
files\musicmatch\musicmatch jukebox\mmjblog.txt" which amongst other things
contains the songs the user has listened to.

--Fix Information--
As of 3/21/05 Yahoo has released a new version which fixes this
vulnerability.  I have witheld vulnerability details until now so that
MusicMatch automatic updates had a chance to propogate.
