MIT Kerberos 5 KDC pkinit_check_kdc_pkid NULL Pointer Dereference (CVE-2013-1415)

A denial-of-service vulnerability has been reported in the MIT Kerberos 5 KDC server. The vulnerability is due to a free of a NULL pointer in the pkinitcheckkdcpkid function while processing malformed requests. A remote unauthenticated attacker can exploit this vulnerability by sending specially...
