Topic

An update for jboss-ec2-eap is now available for Red Hat JBoss Enterprise Application Platform 6.4 for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

The jboss-ec2-eap packages provide scripts for Red Hat JBoss Enterprise Application Platform running on the Amazon Web Services (AWS) Elastic Compute Cloud (EC2).

With this update, the jboss-ec2-eap package has been updated to ensure compatibility with Red Hat JBoss Enterprise Application Platform 6.4.18.

Security Fix(es):

• It was found that while parsing the SAML messages the StaxParserUtil class of Picketlink replaces special strings for obtaining attribute values with system property. This could allow an attacker to determine values of system properties at the attacked system by formatting the SAML request ID field to be the chosen system property which could be obtained in the "InResponseTo" field in the response. (CVE-2017-2582)

This issue was discovered by Hynek Mlnarik (Red Hat).
