When the KDC receives certain TGS-REQ messages, it may dereference an
uninitialized pointer while processing authorization data, causing a
crash, or in rare cases, unauthorized information disclosure, ticket
modification, or execution of arbitrary code.  The crash may be
triggered by legitimate requests.

Correctly implement the filtering of authorization data items to avoid
leaving uninitialized pointers when omitting items.
