Description Mark J. Cox 2005-08-30 11:46:14 UTC 
A flaw was found in Apache 2.0 where the byterange filter would buffer responses
into memory.  This could cause a Denial of Service through memory leak if a
remote attacker sends carefully crafted requests to a web server that has a CGI
script which usually would give a large response.
