tag_insight = "The Apache Portable Runtime (APR) is a portability library used by the
  Apache HTTP Server and other projects. It provides a free library of C data
  structures and routines.

  The fix for CVE-2011-0419 (released via RHSA-2011:0507) introduced an
  infinite loop flaw in the apr_fnmatch() function when the APR_FNM_PATHNAME
  matching flag was used. A remote attacker could possibly use this flaw to
  cause a denial of service on an application using the apr_fnmatch()
  function. (CVE-2011-1928)
  
  Note: This problem affected httpd configurations using the "Location"
  directive with wildcard URLs. The denial of service could have been
  triggered during normal operation; it did not specifically require a
  malicious HTTP request.
  
  This update also addresses additional problems introduced by the rewrite of
  the apr_fnmatch() function, which was necessary to address the
  CVE-2011-0419 flaw.
  
  All apr users should upgrade to these updated packages, which contain a
  backported patch to correct this issue. Applications using the apr library,
  such as httpd, must be restarted for this update to take effect.";
