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].

CVE-2013-1418 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1418): The setup_server_realm function in main.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.7, when multiple realms are configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted request.
GLSA vote: yes.
Whoops, didn't see that I had already added this. Fail.
