Who is Vulnerable?
Vulnerability Description	NullSoft Winamp is a multimedia player that is capable of playing back many audio/video formats and streaming protocols. Winamp supports the Ultravox media streaming format, a proprietary streaming media protocol developed by AOL. There exists a buffer overflow vulnerability in Nullsoft Winamp Player. The vulnerability is due to boundary errors when parsing metadata in Ultravox streaming protocol. An attacker may exploit the vulnerability by enticing a user to visit a malicious server with the affected product, resulting in execution of arbitrary code on the target host within the security context of the currently logged in user. In case of an attack where code injection is not successful, the affected application may terminate upon processing of the malicious Ultravox Streaming Metadata. In case of an attack where code injection and execution is successful, the behavior of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the currently logged in user.
