The remote host is vulnerable to a buffer overflow.
The remote client is running a version of the Nullsoft Winamp media player that may be vulnerable to a remote buffer overflow. This vulnerability may be used to remotely execute arbitrary code on the host by invoking a malicious playlist. IN_CDDA.dll will fail to parse it correctly and an attacker will be able to exploit the buffer overflow.
Upgrade to Winamp 5.0.7 or higher.
