The crash may be triggered by legitimate requests. Correctly implement the filtering of authorization data items to avoid leaving uninitialized pointers when omitting items. https://github.com/krb5/krb5/commit/315147a989c6fde20e09a69711fda1bc5cc5fcaa Commit By: tlyu Revision: 24431 Changed Files: U branches/krb5-1-8/src/kdc/kdc_authdata.c
