Description:


   MIT kerberos krb5 was updated to fix several security issues and bugs.

   Security issues fixed: CVE-2014-5351: The kadm5_randkey_principal_3
   function in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5
   (aka krb5) sent old keys in a response to a -randkey -keepold request,
   which allowed remote authenticated users to forge tickets by leveraging
   administrative access.

   CVE-2014-5352: In the MIT krb5 libgssapi_krb5 library, after
   gss_process_context_token() is used to process a valid context deletion
   token, the caller was left with a security context handle containing a
   dangling pointer.  Further uses of this handle would have resulted in
   use-after-free and double-free memory access violations. libgssrpc server
   applications such as kadmind were vulnerable as they can be instructed to
   call gss_process_context_token().

   CVE-2014-9421: If the MIT krb5 kadmind daemon receives invalid XDR data
   from an authenticated user, it may have performed use-after-free and
   double-free memory access violations while cleaning up the partial
   deserialization results. Other libgssrpc server applications might also
   been vulnerable if they contain insufficiently defensive XDR functions.

   CVE-2014-9422: The MIT krb5 kadmind daemon incorrectly accepted
   authentications to two-component server principals whose first component
   is a left substring of "kadmin" or whose realm is a left prefix of the
   default realm.

   CVE-2014-9423: libgssrpc applications including kadmind output four or
   eight bytes of uninitialized memory to the network as part of an unused
   "handle" field in replies to clients.

   Bugs fixed:
   - Work around replay cache creation race; (bnc#898439).
