high Nessus Plugin ID 18834

Synopsis

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

Description

A MIT krb5 Security Advisory reports :

The MIT Kerberos 5 administration library (libkadm5srv) contains a heap buffer overflow in password history handling code which could be exploited to execute arbitrary code on a Key Distribution Center (KDC) host. The overflow occurs during a password change of a principal with a certain password history state. An administrator must have performed a certain password policy change in order to create the vulnerable state.

An authenticated user, not necessarily one with administrative privileges, could execute arbitrary code on the KDC host, compromising an entire Kerberos realm.

Solution

Update the affected packages.
