"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 security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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."
