Summary

as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.17,
and includes bug fixes and enhancements, which are documented in the
Release Notes document linked to in the References.
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).
