# Acoustica Beatcraft (bcproj file) Local BOF Exploit
# Author: Koshi
#
# Date: 08-30-08 ( 0day )
# Application: Acoustica Beatcraft
# Version(s): v1.02 Build 19
# Site: http://acoustica.com/beatcraft/index.htm
# Tested On: Windows XP SP3 Fully Patched
#
# Acoustica Beatcraft contains a buffer prone to exploitation via an
# overly long string. The buffer contains the "title" of the "instruments"
# one can insert into a Beatcraft project. This exploit is a bit
# unstable in the fact that, to properly exploit it, one must open
# Beatcraft firstly, then proceed to open the exploit file from
# within Beatcraft. Simply double clicking the file will result
# in a simple DoS scenario. ( Hopefully I'll fix this soon )
# My guess as of now is we're not going to have it both ways.
