Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

An advisory published by the MIT Kerberos team says :

The MIT Kerberos 5 Key Distribution Center (KDC) daemon is vulnerable
to a double-free condition if the Public Key Cryptography for Initial
Authentication (PKINIT) capability is enabled, resulting in daemon
crash or arbitrary code execution (which is believed to be difficult).

An unauthenticated remote attacker can induce a double-free event,
causing the KDC daemon to crash (denial of service), or to execute
arbitrary code. Exploiting a double-free event to execute arbitrary
code is believed to be difficult.
