A flaw was found in the way the Apache HTTP Server handled Range HTTP
headers. A remote attacker could use this flaw to cause httpd to use
an excessive amount of memory and CPU time via HTTP requests with a
specially crafted Range header. (CVE-2011-3192)

All httpd users should upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
updated packages, the httpd daemon must be restarted for the update to
take effect."
