+Subject: [PATCH] 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.
