Ubuntu Security Notice USN-282-1	       May 08, 2006
nagios vulnerability
CVE-2006-2162
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

nagios-common

The problem can be corrected by upgrading the affected package to
version 2:1.3-0+pre6ubuntu0.1 (for Ubuntu 5.04), or
2:1.3-cvs.20050402-4ubuntu3.1 (for Ubuntu 5.10).  In general, a
standard system upgrade is sufficient to effect the necessary changes.

Details follow:

The nagios CGI scripts did not sufficiently check the validity of the
HTTP Content-Length attribute. By sending a specially crafted HTTP
request with a negative 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.
