  script_tag(name:"insight", value:"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.

  It was discovered that the apr_fnmatch() function used an unconstrained
  recursion when processing patterns with the '*' wildcard. An attacker could
  use this flaw to cause an application using this function, which also
  accepted untrusted input as a pattern for matching (such as an httpd server
  using the mod_autoindex module), to exhaust all stack memory or use an
  excessive amount of CPU time when performing matching. (CVE-2011-0419)

  Red Hat would like to thank Maksymilian Arciemowicz for reporting this
  issue.

  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.");
