Summary

On NGINX Controller versions 3.1.0-3.3.0, AVRD uses world-readable and world-writable permissions on its socket, which allows processes or users on the local system to write arbitrary data into the socket. A local system attacker can make AVRD segmentation fault (SIGSEGV) by writing malformed messages to the socket.
