"The nagios CGI scripts did not sufficiently check the validity of the
HTTP Content-Length attribute. By sending a specially crafted HTTP
request with an invalidly large Content-Length value to the Nagios
server, a remote attacker could exploit this to execute arbitrary code
with web server privileges.

Please note that the Apache 2 web server already checks for valid
Content-Length values, so installations using Apache 2 (the only web
server officially supported in Ubuntu) are not vulnerable to this
flaw.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
