Verify decoded kadmin C strings [CVE-2015-8629] 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.
