CVE-2007-0086
Published Jan 5, 2007

Overview
- Description
- The Apache HTTP Server, when accessed through a TCP connection with a large window size, allows remote attackers to cause a denial of service (network bandwidth consumption) via a Range header that specifies multiple copies of the same fragment. NOTE: the severity of this issue has been disputed by third parties, who state that the large window size required by the attack is not normally supported or configured by the server, or that a DDoS-style attack would accomplish the same goal

Vendor comments
- Red HatRed Hat does not consider this issue to be a security vulnerability. The pottential attacker has to send acknowledgement packets periodically to make server generate traffic. Exactly the same effect could be achieved by simply downloading the file. The statement that setting the TCP window size to arbitrarily high value would permit the attacker to disconnect and stop sending ACKs is false, because Red Hat Enterprise Linux limits the size of the TCP send buffer to 4MB by default.
