Summary: Updated rhpki-util, rhpki-common, and rhpki-ca packages that fix a security issue and several bugs are 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: Red Hat Certificate System (RHCS) is an enterprise software system designed to manage enterprise Public Key Infrastructure (PKI) deployments. It was discovered that new revocations, performed while a Certificate Revocation List (CRL) was being generated, could potentially cause revoked certificates at the upper end of the serial number range to not appear on the CRL for a period of time. A user who has a revoked but otherwise valid certificate could take advantage of this issue and bypass the revocation list; however, in practice, they would have no way of influencing which revoked certificate entries were missing or the time period. (CVE-2007-4994) As well, these updated packages fix the following bugs: * due to a regression, signing a CRL with approximately 150,000 records may have taken up to five minutes. In these updated packages, signing such CRLs takes approximately twenty seconds. * a bug, which resulted in a 404 error, due to servers not handling Online Certificate Status Protocol (OCSP) requests in the GET method, has been resolved. This issue may have caused a system to use 100% CPU. As well, OCSP requests are now logged to the debug log file. * it was possible for a CRL update to run at the same time as a certificate status update. Now, CRL updating locks out the certificate status update thread. * inefficient LDAP search methods caused LDAP searches for a large number of revoked certificates to take up to twenty minutes or more for 100,000 certificates during CRL generation. The LDAP search method has been modified to greatly improve LDAP search times. * the default OCSP verification path has changed since RHCS 7.1. These updated packages add support for certificates that use the old AuthorityInfoAccess (AIA) URL. * an OCSP client submitting an OCSP request via the GET method may have caused a "NullPointerException". * if an agent automatically approved a certificate signing request (CSR), using AgentCertAuth, the resultant certificate contained blank Subject Alt Name extension fields. A manual enrollment by the same agent produced a certificate with the correct number of Subject Alt Names and no blank entries. With this update, automated enrollments via AgentCertAuth do not have blank fields in issued certificates. Users of Red Hat Certificate System should upgrade to these updated packages, which resolve these issues. 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: Updated Solaris packages in .pkg format are available in the Red Hat Certificate System Solaris channels on the Red Hat Network. These packages should be installed/upgraded using Solaris native package management tools.
