Ubuntu Security Notice USN-1151-1
June 15, 2011

nagios3 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS


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


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.

  CVE-2011-1523, CVE-2011-2179
