Your friendly security team received the following report via security@suse.de.
Please respond ASAP.
This issue is not public yet, please keep any information about it inside SUSE.

It was found that krb5's KDC since version 1.9 could be made to crash on a NULL pointer deref. Remote authenticated users could exploit that to crash KDC.
