+Subject: [PATCH 3/3] Fix leaks in kadmin server stubs [CVE-2015-8631]
+
+In each kadmind server stub, initialize the client_name and
+server_name variables, and release them in the cleanup handler.  Many
+of the stubs will otherwise leak the client and server name if
+krb5_unparse_name() fails.  Also make sure to free the prime_arg
+variables in rename_principal_2_svc(), or we can leak the first one if
+unparsing the second one fails.  Discovered by Simo Sorce.
+
+CVE-2015-8631:
+
+In all versions of MIT krb5, an authenticated attacker can cause
+kadmind to leak memory by supplying a null principal name in a request
+which uses one.  Repeating these requests will eventually cause
+kadmind to exhaust all available memory.
