Ubuntu 5.04 / 5.10 : nagios vulnerability (USN-287-1)

high Nessus Plugin ID 21612

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Solution

Update the affected packages.
