1. Summary:

An update to the Node.js adapter for Red Hat Single Sign-On 7.1 is now
available from the Customer Portal.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,

from the CVE link(s) in the References section.

2. Description:

Red Hat Single Sign-On 7.1 is a standalone server, based on the Keycloak
project, that provides authentication and standards-based single sign-on
capabilities for web and mobile applications. The Node.js adapter provides
a simple module for authentication and authorization in Node.js
applications.

This asynchronous patch is a security update for the Node.js adapter for
Red Hat Single Sign-On 7.1.

Security Fix(es):

* It was found that the Keycloak Node.js adapter did not handle invalid
tokens correctly. An attacker could use this flaw to bypass authentication
and gain access to restricted information, or to possibly conduct further
attacks. (CVE-2017-7474)

Red Hat would like to thank Nick Shearer (Quest) for reporting this issue.

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). 

Remove your existing Node.js adapter directory and unzip the update file
into its place. Then change the dependency for keycloak-connect in the
package.json of your application: change dependency file name to
keycloak-connect-2.5.5-Final-redhat-3.tgz .
