Nagios vulnerability

Releases

• Ubuntu 5.10
• Ubuntu 5.04

Details

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.
