  - CVE-2013-6438: XML parsing code in mod_dav incorrectly calculates the end of the string when
  removing leading spaces and places a NUL character outside the buffer, causing random crashes.
  This XML parsing code is only used with DAV provider modules that support DeltaV, of which the
  only publicly released provider is mod_dav_svn.

  - CVE-2014-0098: A flaw was found in mod_log_config. A remote attacker could send a specific
  truncated cookie causing a crash. This crash would only be a denial of service if using a
  threaded MPM.");
