-
-In xdr_nullstring(), check that the decoded string is terminated with
-a zero byte and does not contain any internal zero bytes.
-
-CVE-2015-8629:
-
-In all versions of MIT krb5, an authenticated attacker can cause
-kadmind to read beyond the end of allocated memory by sending a string
-without a terminating zero byte.  Information leakage may be possible
-for an attacker with permission to modify the database.

-In kadm5_create_principal_3() and kadm5_modify_principal(), check for

-
-CVE-2015-8630:

-Subject: [PATCH] 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.

-Subject: [PATCH] Fix LDAP null deref on empty arg [CVE-2016-3119]
-
-In the LDAP KDB module's process_db_args(), strtok_r() may return NULL
-if there is an empty string in the db_args array.  Check for this case
-and avoid dereferencing a null pointer.
-
-CVE-2016-3119:
-
-In MIT krb5 1.6 and later, an authenticated attacker with permission
-to modify a principal entry can cause kadmind to dereference a null
-pointer by supplying an empty DB argument to the modify_principal
-command, if kadmind is configured to use the LDAP KDB module.
