Brief History \ :
+---------------`-------------------------------------------------------.
You are affected if you have RealPlayer installed on 2K and your :
browser open MP3 file using RealPlayer. :
:
+---------------------------+ :
>>> Test OS Applications <<< :
+---------------------------+ :
Tested on Windows 2K, XP with Realplayer Plys 8 Installed. Maybe other :
versions of Realplayer are affected too. I do not have other versions :
:
:
+-----------. :
The Problem \ :
+-------------`---------------------------------------------------------.
To see the problem do the following steps: :
1- Make sure you have Windows RealPlayer installed :
2- Make sure that .mp3 file will be opened using Realplayer. Normaly :
this is the default after you install Realplayer. :
3- Take any non .mp3 file say virus.exe rename it to virus.mp3 :
4- Create an HTML file that open test.mp3 :
<p><a href="test.mp3">test</a></p> :
5- Put the files test.mp3 and test.html on your web server :
6- Open http://www.yourwebserver.com/test.html :
7- HIT CTRL+DEL+ALT and check your CPU it should be 100 % if Realplayer :
open. :
:
I have a test page on www.safehack.com/testpage/test1.htm :
:
The problem is Realplayer will open and will try to connect and play :
the NON valid mp3 file. :
:
This issue does not happen if your default mp3 player is winamp or ohter:
:
Another behavior I did notice id the html link point to file.exe.mp3 :
<p><a href="test.exe.mp3">test</a></p> in this case Winamp will open :
not Realplayer. :
I have a test page on www.safehack.com/testpage/test2.htm :
:
This test page will open Winamp even if your default is Realplayer :
:
+------------. :
The Solution \ :
+--------------`--------------------------------------------------------.
Don't Make Realplayer your default to open mp3 files :
+-----------------------------------------------------------------------.
