Who is Vulnerable?
Vulnerability Description	Nullsoft Winamp is a multimedia player application that is capable of playing many formats of audio and video files. Winamp can play CD tracks, MP3 music files or MPEG video files as well as numerous other formats. It is also capable of reading AIFF media file which has file extension "aiff". A vulnerability exists in the AIFF file parsing component of Nullsoft Winamp. The vulnerability is caused by improper handling of the header of AIFF media files. A remote attacker can exploit this vulnerability by enticing the user to open a crafted AIFF file, thereby creating a denial of service condition or potentially injecting and executing arbitrary code on the target system. In an attack case where code injection is not successful, the Winamp player will terminate. In an attack scenario where arbitrary code is injected and executed on the target machine, the behaviour of the target host is dependent on the intention of the malicious code. Any code injected into the vulnerable program would execute in the security context of the currently logged in user.
