Synopsis :

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

Description :

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.
