Description

An updated rhpki-common package that fixes a security issue is now available for Red Hat Certificate System 7.3. This update has been rated as having important security impact by the Red Hat Security Response Team.

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 7.3 should upgrade to this updated package, which resolves this issue.
