Who is Vulnerable?
Vulnerability Description	Winamp is a very popular multimedia player, produced by NullSoft, which is capable of playing many formats of audio and video files. One of the audio formats supported by Winamp is Compact-Disc-Digital-Audio (CDDA), which is the format used on standard audio Compact Discs (CD). When an audio CD is inserted into a Windows based system, it presented as a pseudo filesystem containing files with the extension "cda" which represent individual audio tracks. A vulnerability exists in the way Winamp parses playlist files and CD audio files. If a playlist file contains an overly long reference to a file in CD audio format (with a .cda extension) or a CD audio file has a long filename, a buffer overflow can occur in the component IN_CDDA.dll. An attacker can exploit this vulnerability to execute arbitrary code on a vulnerable system by enticing a user to open a specially crafted playlist file or CD audio file. In a simple attack case the Winamp application will terminate with a bad memory address referencing error. The application will not add an entry in the application logs upon termination. In the case of a more sophisticated attack, arbitrary code may be injected into the application and executed. In this case, the behaviour of the attack target will depend on the nature of the injected code.
