frrouting: Misusing strdup leads to stack overflow in isis_nb_notifications.c
Buffer overflow vulnerabilities exist in FRRouting through 8.1.0 due to the use of strdup with a non-zero-terminated binary string in isis_nb_notifications.c.
frrouting is vulnerable to a flaw that can cause stack overflow due to processing binary data as simple string data. Since c string data is not being processed when processing packets , correct binary aware functions should be used. There is high impact to availability due to the fact that the process up-time can be made unreliable.
