Who is Vulnerable?
Vulnerability Description Winamp is a popular multimedia player, produced by Nullsoft, which 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. A vulnerability exists in the MIDI file parsing component of Nullsoft Winamp. The vulnerability is caused by the improper handling of the header of a MIDI media file. A remote attacker can exploit this vulnerability by enticing the user to open a crafted MIDI file, thereby creating a denial of service condition or potentially injecting and executing arbitrary code on the target system. Upon an unsuccessful attack attempting to leverage this vulnerability, the Winamp player will terminate. In an attack scenario where arbitrary code is injected and executed on the target machine, the behavior 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.
