medium Nessus Plugin ID 69066

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

OpenAFS Project reports :

The small size of the DES key space permits an attacker to brute force a cell's service key and then forge traffic from any user within the cell. The key space search can be performed in under 1 day at a cost of around $100 using publicly available services.
