Description

Winamp is prone to an overflow condition. The 'in_midi.dll' plugin fails to properly sanitize user-supplied input when serialising timestamp values, resulting in a stack-based buffer overflow. With a specially crafted MIDI file, a context-dependent attacker can potentially execute arbitrary code.
