Bug description:
  https://secunia.com/advisories/49346/

  Description
  A weakness has been reported in Kerberos, which can be exploited by malicious users to cause a DoS (Denial of Service).

  The vulnerability is caused due to a NULL pointer dereference error in
  the "check_1_6_dummy()" function in src/lib/kadm5/srv/svr_principal.c.
  This can be exploited to cause a crash via a create-principal request
  containing no password but the KRB5_KDB_DISALLOW_ALL_TIX flag.

  Successful exploitation requires an administrator account with
  "create" privileges.

  The weakness is reported in versions prior to 1.10.2.

  
  Solution
  Update to version 1.10.2.

  Provided and/or discovered by
  Reported by the vendor.
