There is no fixed version for Ubuntu:16.04 openafs.

Note: Versions mentioned in the description apply only to the upstream openafs package and not the openafs package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
OpenAFS 1.x before 1.6.22 does not properly validate Rx ack packets, which allows remote attackers to cause a denial of service (system crash or application crash) via crafted fields, as demonstrated by an integer underflow and assertion failure for a small MTU value.
