    landser discovered a vulnerability within the 'remapShader'
    command. Due to a boundary handling error in 'remapShader', there is a
    possibility of a buffer overflow.
  
Impact :

    An attacker could set up a malicious game server and entice users
    to connect to it, potentially resulting in the execution of arbitrary
    code with the rights of the game user.
  
Workaround :

    Do not connect to untrusted game servers."
