Descriptions

The receive_ra function in rdisc/nm-lndp-rdisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in NetworkManager 1.x allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message, a similar issue to CVE-2015-2922.

La función receive_ra en rdisc/nm-lndp-rdisc.c en la implementación del protocolo Neighbor Discovery (ND) en la pila IPv6 en NetworkManager 1.x permite a atacantes remotos reconfigurar un ajuste de límite de salto a través de un valor hop_limit pequeño en un mensaje Router Advertisement (RA), un problema similar a CVE-2015-2922.

A flaw was found in the way NetworkManager handled router advertisements. An unprivileged user on a local network could use IPv6 Neighbor Discovery ICMP to broadcast a non-route with a low hop limit, causing machines to lower the hop limit on existing IPv6 routes. If this limit is small enough, IPv6 packets would be dropped before reaching the final destination.
