1) Insecure File Permissions Local Privilege Escalation  
  
Minecraft's launcher (minecraftLauncher.exe) suffers from an elevation of privileges   
vulnerability which can be used by a simple user that can change the executable file   
with a binary of choice. The vulnerability exist due to the improper permissions,  
with the 'F' flag (Full) for 'Users' group, making the entire directory   
'Minecraft' and its files and sub-dirs world-writable.  
  
This would allow an attacker the ability to inject code or replace the MinecraftLauncher   
executable and have it run in the context of the system.
