 ### Description  
 Code uses a character buffer of 15 allocated bytes to match a password and if it matches the user gets root priveleges (only theoratically). If we input > 15 bytes then the pass variable which is after the allocated character buffer is overwritten and has a non 0 value. Due to this, the password check passes and authentication succeeds even with an incorrect password.
