Introduction
------------
WinAMP is a popular Windows sound player with support for many file
formats (MP3, wave files, modules). It also supports MP3 streaming
(let's call it sh0utcast).
Description of the problem
--------------------------
If we tell WinAMP to open file location (Ctrl+L) which is over 256
bytes long, it'll produce nice GPF. The bug also appears when loading
playlists (.m3u and .pls)
What can we do with this bug?
-----------------------------
Many sh0utcast radios place .pls files on their websites, which contain
URL for radio's sh0utcast server.
If we'll make b00m.pls file like this...
[playlist]
NumberOfEntries=1
File1=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA... (about 256 A's)
and put such link...
<A HREF="b00m.pls">Techno explosion -- The Coolest MP3 Radio</A>
on our website, we can make couple of WinAMPs crash. I suppose, that
there's a possibility to put our own code in the filename (see cDc-351
for details).
Nullsoft (producer of WinAMP) has been noticed about the bug two
versions ago.
