The byte-range 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) using a** Range** header that expresses multiple overlapping ranges.

When this vulnerability is exploited, the httpd process consumes all available CPU cycles. As a result of CPU starvation, the Configuration utility, SSH sessions, and other userland processes may appear extremely slow or completely unresponsive. On BIG-IP systems, if the system hardware watchdog timer is not updated for more than 10 seconds, the hardware watchdog restarts the system.
