Ensure array count consistency in kadm5 RPC
In _xdr_kadm5_principal_ent_rec(), ensure that n_key_data matches the
key_data array count when decoding. Otherwise when the structure is
later freed, xdr_array() could iterate over the wrong number of
elements, either leaking some memory or freeing uninitialized
pointers. Reported by Robert Morris.
CVE-2023-36054:
An authenticated attacker can cause a kadmind process to crash by
freeing uninitialized pointers. Remote code execution is unlikely.
An attacker with control of a kadmin server can cause a kadmin client
to crash by freeing uninitialized pointers.
