Apache HTTP Server 1.3.x 2.0.35-2.0.64 2.2.0-2.2.19 - Denial of Service via Range Header Overlap
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.
