An advisory published by the MIT Kerberos team says:

The MIT Kerberos 5 implementation's Key Distribution Center (KDC) program contains a double-free vulnerability that potentially allows a remote attacker to execute arbitrary code. Compromise of a KDC host compromises the security of the entire authentication realm served by the KDC. Additionally, double-free vulnerabilities exist in MIT Kerberos 5 library code, making client programs and application servers vulnerable.

Double-free vulnerabilities of this type are not believed to be exploitable for code execution on FreeBSD systems. However, the potential for other ill effects may exist.
