Description:
Brett Moore has reported a vulnerability in Winamp, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the "IN_CDDA.dll" file. This can be exploited in various ways to cause a stack-based buffer overflow e.g. by tricking a user into visiting a malicious web site containing a specially crafted ".m3u" playlist.
Successful exploitation allows execution of arbitrary code.
The vulnerability has been reported in version 5.05 and confirmed in version 5.06. Prior versions may also be affected.
Solution:
Disassociate ".cda" and ".m3u" extensions from Winamp.
