Important: krb5

Issue Overview:

An uninitialized pointer use flaw was found in the way the MIT Kerberos KDC handled initial authentication requests (AS-REQ). A remote, unauthenticated attacker could use this flaw to crash the KDC via a specially-crafted AS-REQ request. (CVE-2012-1015)

A NULL pointer dereference flaw was found in the MIT Kerberos administration daemon, kadmind. A Kerberos administrator who has the “create” privilege could use this flaw to crash kadmind. (CVE-2012-1013)
