CVE-2011-3192
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.");
