Synopsis :

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

Description :

The MIT Kerberos team reports :

MIT krb5 incorrectly accepts an unkeyed checksum for PAC signatures.

An authenticated remote attacker can forge PACs if using a KDC that
does not filter client-provided PAC data. This can result in privilege
escalation against a service that relies on PAC contents to make
authorization decisions.
