## Description

The byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64,
and 2.2.x through 2.2.19 allows remote attackers to cause a denial of
service (memory and CPU consumption) via a Range header that expresses
multiple overlapping ranges, as exploited in the wild in August 2011, a
different vulnerability than CVE-2007-0086.
