- Issue #18709: Fix CVE-2013-4238. The SSL module now handles NULL bytes 

  inside subjectAltName correctly. Formerly the module has used OpenSSL's
  GENERAL_NAME_print() function to get the string represention of ASN.1
  strings for `rfc822Name` (email), `dNSName` (DNS) and
  `uniformResourceIdentifier` (URI).
