582466: CVE-2010-1321 krb5: null pointer dereference in GSS-API library leads to DoS (MITKRB5-SA-2010-005)

The MITRE CVE dictionary describes this issue as:

The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.
