  for a standard apache, the configuration files provided with apache and
  apache-ssl are unchanged.

Problem description:
  Stack-based buffer overflow in the ssl_util_uuencode_binary function
  in ssl_util.c for Apache mod_ssl when mod_ssl is configured to trust
  the issuing CA, may allow remote attackers to execute arbitrary code
