FreeBSD : kauth: Local privilege escalation (0baee383-356c-11e7-b9a9-50e549ebab6c)

high Nessus Plugin ID 100113

Language:

Synopsis

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

Description

Albert Astals Cid reports :

KAuth contains a logic flaw in which the service invoking dbus is not properly checked. This allows spoofing the identity of the caller and with some carefully crafted calls can lead to gaining root from an unprivileged account.

Solution

Update the affected packages.
