Description

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.

Affected products

• NGINX Controller: from 3.1.0 before 3.4.0 — fixed in 3.4.0

How to fix

Upgrade to a fixed version: NGINX Controller 3.4.0. Check the vendor advisory for mitigations.
