Summary: An updated rhpki-ra package that fixes one security issue is now available for Red Hat Certificate System 7.3. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Certificate System 7.3 for 4AS - noarch Red Hat Certificate System 7.3 for 4ES - noarch 3. Description: The Red Hat registration authority is an optional Red Hat Certificate System subsystem that acts as a front-end for authenticating and processing enrollment requests, PIN reset requests, and formatting requests. Robert Mead of AusCERT reported that the registration authority did not properly check an agent's authorization in some CGI scripts. In deployments where certificate requests were processed by multiple agent groups, an agent from any group was able to approve or reject certificate requests in the queue for any other agent group, if they were able to guess the request ID. (CVE-2009-0588) All Red Hat Certificate System 7.3 users should upgrade to this updated package, which resolves this issue. 4. Solution: Users running Red Hat Certificate System on Red Hat Enterprise Linux: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 Users running Red Hat Certificate System on Sun Solaris: An updated Solaris package, in .pkg format, is available in the Red Hat Certificate System Solaris channel on the Red Hat Network. Use native Solaris package management tools to install or upgrade this package. After applying the updated package on both Linux and Solaris, copy the op.cgi file to the corresponding instance locations, for example: # cp /usr/share/rhpki/ra/docroot/agent/request/op.cgi /var/lib/rhpki-ra/docroot/agent/request/op.cgi For detailed installation instructions, see the "Installation and Configuration" section of the Red Hat Certificate System 7.3 Administration Guide: http://redhat.com/docs/manuals/cert-system/7.3/html/Administration_Guide/ 5.
