Summary: Updated rhpki-common packages that fix a security issue are now available for Red Hat Certificate System 7.2. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Certificate System 7.2 for 4AS - noarch Red Hat Certificate System 7.2 for 4ES - noarch 3. Description: Red Hat Certificate System (RHCS) is an enterprise software system designed to manage enterprise Public Key Infrastructure (PKI) deployments. rhpki-common -- the Red Hat PKI Common Framework -- is required by the following four RHCS subsystems: the Red Hat Certificate Authority; the Red Hat Data Recovery Manager; the Red Hat Online Certificate Status Protocol Manager; and the Red Hat Token Key Service. A flaw was found in the way Red Hat Certificate System handled Extensions in the certificate signing requests (CSR). All requested Extensions were added to the issued certificate even if constraints were defined in the Certificate Authority (CA) profile. An attacker could submit a CSR for a subordinate CA certificate even if the CA configuration prohibited subordinate CA certificates. This lead to a bypass of the intended security policy, possibly simplifying man-in-the-middle attacks against users that trust Certificate Authorities managed by Red Hat Certificate System. (CVE-2008-1676) All users of Red Hat Certificate System 7.2 should upgrade to these updated packages, which resolves this issue. 4. Solution: Users running Red Hat Certificate System on Red Hat Enterprise Linux: Before applying this update, make sure that 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/FAQ_58_10188 Users running Red Hat Certificate System on Sun Solaris: An updated Solaris packages in .pkg format are available in the Red Hat Certificate System Solaris channels on the Red Hat Network.
