The remote host is vulnerable to a Denial of Service (DoS) attack.
The remote host is running Lighttpd, a small web server. This version of Lighttpd is vulnerable to multiple Denial of Service (DoS) flaws. An attacker exploiting these flaws would only need to be able to send data to the web server. Successful exploitation would result in the attacker crashing the web server.
Upgrade to version 1.4.14 or higher.
