In this case, if either the username or password decoded from the authorization string exceeds `40` characters (the size the stack variables `username` and `password`) then a stack overflow will occur. \n\n\n\nThe data is controlled by an attacker, but sronger constraints (e.g. no null bytes) may make exploitation harder.
