Advisory ID:       RHSA-2009:0006-01
Product:           Red Hat Certificate System
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-0006.html

CVE Names:         CVE-2008-2367 CVE-2008-2368 
=====================================================================

1. Summary:

Updated pkisetup, rhpki-common, rhpki-ca, rhpki-kra, rhpki-ocsp, rhpki-tks,
and rhpki-tps (and rhpki-util for Solaris 9) packages that fix various
security issues and several bugs are now available for Red Hat Certificate
System 7.2.

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 7.2 for 4AS - i386, noarch, x86_64
Red Hat Certificate System 7.2 for 4ES - i386, noarch, x86_64

3. Description:

Red Hat Certificate System is an enterprise software system designed to
manage enterprise public key infrastructure (PKI) deployments.

It was discovered that Red Hat Certificate System used insecure default
file permissions on certain configuration files (for example,
password.conf) that may contain authentication credentials. These 
credentials should only be accessible to administrative and service users. 
A local user could use this flaw to read Red Hat Certificate System 
configuration files containing sensitive information. (CVE-2008-2367)

It was discovered that Red Hat Certificate System stored plain text
passwords in multiple debug log files with insufficient access restrictions
(such as the UserDirEnrollment log and RA wizard installer log). A local
user could use this flaw to extract plain text passwords from the Red Hat
Certificate System debug log files. (CVE-2008-2368)

These updated packages fix the following bugs:

* Due to a regression, signing a certificate revocation list (CRL) with
approximately 150,000 records may have taken up to five minutes. In these
updated packages, signing such CRLs takes approximately twenty seconds.

* Because Certificate System servers could not handle Online Certificate 
Status Protocol (OCSP) requests in the GET method, OCSP GET requests 
resulted in a 404 error. The bug for handling GET requests may have also 
caused a system to use 100% CPU. This has been resolved. Additionally, 
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 100,000 or 
more revoked certificates to take twenty minutes or longer during CRL 
generation. The LDAP search method has been modified to greatly improve 
LDAP search times.

* The default OCSP verification path has changed since Red Hat Certificate
System 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 
subjectAltName extension fields. A manual enrollment by the same agent 
produced a certificate with the correct number of subjectAltNames and no 
blank entries. With this update, automated enrollments through 
AgentCertAuth do not have blank fields in issued certificates.

All users of Red Hat Certificate System 7.2 should upgrade to these updated
packages, which resolve these issues.
