Synopsis :

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

Description :

Two vulnerabilities in krb5 can be used by remote attackers in denial
of service attacks. The MIT security advisories report this as follows
:

An unauthenticated remote attacker can send an invalid request to a
KDC process that will cause it to crash due to an assertion failure,
creating a denial of service.

An unauthenticated remote attacker could cause a GSS-API application,
including the Kerberos administration daemon (kadmind) to crash.
