FreeBSD : Incorrect cross-realm trust handling in Heimdal (bfb36941-84fa-11d8-a41f-0020ed76ef5a)

medium Nessus Plugin ID 37254

Synopsis

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

Description

Heimdal does not correctly validate the `transited' field of Kerberos tickets when computing the authentication path. This could allow a rogue KDC with which cross-realm relationships have been established to impersonate any KDC in the authentication path.

Solution

Update the affected package.
