Synopsis

The remote Red Hat host is missing a security update for ipa.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:1533 advisory.

Red Hat Identity Management is a centralized authentication, identity management and authorization solution for both traditional and cloud based enterprise environments. It integrates components of the Red Hat Directory Server, MIT Kerberos, Red Hat Certificate System, NTP and DNS. It provides web browser and command-line interfaces. Its administration tools allow an administrator to quickly install, set up, and administer a group of domain controllers to meet the authentication and identity management requirements of large scale Linux and UNIX deployments.

A Cross-Site Request Forgery (CSRF) flaw was found in Red Hat Identity Management. If a remote attacker could trick a user, who was logged into the management web interface, into visiting a specially-crafted URL, the attacker could perform Red Hat Identity Management configuration changes with the privileges of the logged in user. (CVE-2011-3636)

Due to the changes required to fix CVE-2011-3636, client tools will need to be updated for client systems to communicate with updated Red Hat Identity Management servers. New client systems will need to have the updated ipa-client package installed to be enrolled. Already enrolled client systems will need to have the updated certmonger package installed to be able to renew their system certificate. Note that system certificates are valid for two years by default.

Updated ipa-client and certmonger packages for Red Hat Enterprise Linux 6 were released as part of Red Hat Enterprise Linux 6.2. Future updates will provide updated packages for Red Hat Enterprise Linux 5.

This update includes several bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.2 Technical Notes for information on the most significant of these changes, linked to in the References section.

Users of Red Hat Identity Management should upgrade to these updated packages, which correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL ipa package based on the guidance in RHSA-2011:1533.
