Red Hat Security Advisory

Synopsis: Moderate: pki-core security, bug fix and enhancement update
Advisory ID: RHSA-2013:0511-02
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0511.html
Issue date: 2013-02-21
CVE Names: CVE-2012-4543
=====================================================================

1. Summary:

Updated pki-core packages that fix multiple security issues, two bugs, and
add various enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - noarch
Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch

3. Description:

Red Hat Certificate System is an enterprise software system designed to
manage enterprise public key infrastructure (PKI) deployments. PKI Core
contains fundamental packages required by Red Hat Certificate System, which
comprise the Certificate Authority (CA) subsystem.

Note: The Certificate Authority component provided by this advisory cannot
be used as a standalone server. It is installed and operates as a part of
Identity Management (the IPA component) in Red Hat Enterprise Linux.

Multiple cross-site scripting flaws were discovered in Certificate System.
An attacker could use these flaws to perform a cross-site scripting (XSS)
attack against victims using Certificate System's web interface.
(CVE-2012-4543)

This update also fixes the following bugs:

* Previously, due to incorrect conversion of large integers while
generating a new serial number, some of the most significant bits in the
serial number were truncated. Consequently, the serial number generated for
certificates was sometimes smaller than expected and this incorrect
conversion in turn led to a collision if a certificate with the smaller
number already existed in the database. This update removes the incorrect
integer conversion so that no serial numbers are truncated. As a result,
the installation wizard proceeds as expected. (BZ#841663)

* The certificate authority used a different profile for issuing the audit
certificate than it used for renewing it. The issuing profile was for two
years, and the renewal was for six months. They should both be for two
years. This update sets the default and constraint parameters in the
caSignedLogCert.cfg audit certificate renewal profile to two years.
(BZ#844459)

This update also adds the following enhancements:

* IPA (Identity, Policy and Audit) now provides an improved way to
determine that PKI is up and ready to service requests. Checking the
service status was not sufficient. This update creates a mechanism for
clients to determine that the PKI subsystem is up using the getStatus()
function to query the cs.startup_state in CS.cfg. (BZ#858864)

* This update increases the default root CA validity period from eight
years to twenty years. (BZ#891985)

All users of pki-core are advised to upgrade to these updated packages,
which fix these issues and add these enhancements.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

858864 - create/ identify a mechanism for clients to determine that the pki
subsystem is up
864397 - CVE-2012-4543 Certificate System: Multiple cross-site scripting flaws
by displaying CRL or processing profile
867640 - ipa-replica-install Configuration of CA failed
891985 - Increase FreeIPA root CA validity
