PKINIT (draft9) null ptr deref [CVE-2012-1016]
Don't check for an agility KDF identifier in the non-draft9 reply
structure when we're building a draft9 reply, because it'll be NULL.
The KDC plugin for PKINIT can dereference a null pointer when handling
a draft9 request, leading to a crash of the KDC process. An attacker
would need to have a valid PKINIT certificate, or an unauthenticated
attacker could execute the attack if anonymous PKINIT is enabled.
