CVE-2011-3192 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 98.95% chance of exploitation in the next 30 days.
