Detail

Problem Description:

Updated ipa packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Id Description
77568 FreeIPA Configuration Manipulation CSRF

FreeIPA contains a flaw that allows a remote Cross-site Request Forgery (CSRF / XSRF) attack. The flaw exists because the application does not require multiple steps or explicit confirmation for sensitive transactions for the manipulation of configuration options. By using a crafted URL (e.g., a crafted GET request inside an "img" tag), an attacker may trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into executing arbitrary commands in the context of their session with the application, without further prompting or verification.
