1. Summary:

Updated pki-common, pki-tps and pki-util packages that fix multiple
security issues and add one enhancement are now available for Red Hat
Certificate System 8.1.

The Red Hat Security Response Team has rated this update as having moderate

3. Description:

Red Hat Certificate System is an enterprise software system designed to
manage enterprise Public Key Infrastructure (PKI) deployments.

Multiple cross-site scripting flaws were discovered in the Red Hat
Certificate System Agent and End Entity pages. An attacker could use these
flaws to perform a cross-site scripting (XSS) attack against victims using
Certificate System's web interface. (CVE-2012-2662)

It was discovered that Red Hat Certificate System's Certificate Manager
did not properly check certificate revocation requests performed via its
web interface. An agent permitted to perform revocations of end entity
certificates could use this flaw to revoke the Certificate Authority (CA)
certificate. (CVE-2012-3367)

This update also adds the following enhancement:

* Red Hat Certificate System 8.1 did not previously allow using Red Hat
Directory Server 9.0 as its internal database. This update adds support
for Directory Server 9.0. (BZ#547527, BZ#819508)

All users of Red Hat Certificate System 8.1 are advised to upgrade to these
updated packages, which correct these issues and add this enhancement.
After installing this update, all Red Hat Certificate System subsystems
must be restarted for the update to take effect.
