CVE-2013-1418: Null Pointer Dereference
First published: Tue Nov 05 2013(Updated: )
It was reported [1] that if a KDC serves multiple realms, certain requests could cause the setup_server_realm() funtion to dereference a null pointer, resulting in a crash of the KDC (Key Distribution Center). This can be triggered by an unauthenticated user. This has been correct in git [2].
