 ticket: 6797
 subject: CVE-2010-1322 KDC uninitialized pointer crash in authorization data handling (MITKRB5-SA-2010-006)
 tags: pullup
 target_version: 1.8.4

 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.
