Ubuntu Security Notice USN-2042-2 deals with vulnerabilities in apache2 that could enable unauthorized access via manipulated requests.
An attacker could modify or steal data if you were tricked into clicking on a special link to Nagios.

Summary

An attacker could modify or steal data if you were tricked into clicking on

a special link to Nagios.

Software Description:

- nagios3: A host/service/network monitoring and management system

Details:

Stefan Schurtz discovered than Nagios did not properly sanitize its input

when processing certain requests, resulting in cross-site scripting (XSS)

vulnerabilities. With cross-site scripting vulnerabilities, if a user were

tricked into viewing server output during a crafted server request, a

remote attacker could exploit this to modify the contents, or steal

confidential data, within the same domain.

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
  nagios3-cgi                     3.2.3-1ubuntu1.2

Ubuntu 10.10:
  nagios3-cgi                     3.2.1-2ubuntu1.2

Ubuntu 10.04 LTS:
  nagios3-cgi                     3.2.0-4ubuntu2.2

After a standard system update you need to restart Nagios to make
all the necessary changes.
