The eap7-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 eap7-jboss-ec2-eap package has been updated to
ensure compatibility with Red Hat JBoss Enterprise Application
Platform 7.0.8.

Refer to the JBoss Enterprise Application Platform 7.0.8 Release
Notes, linked to in the References section, for information on the
most significant bug fixes and enhancements included in this release.

Security Fix(es) :

* It was found that when using remote logging with log4j socket server
the log4j server would deserialize any log event received via TCP or
UDP. An attacker could use this flaw to send a specially crafted log
event that, during deserialization, would execute arbitrary code in
the context of the logger application. (CVE-2017-5645)

* A vulnerability was found in Jasypt that would allow an attacker to
perform a timing attack on password hash comparison. (CVE-2014-9970)

* It was found that an information disclosure flaw in Bouncy Castle
could enable a local malicious application to gain access to user's
private information. (CVE-2015-6644)

* 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)

* It was found that when the security manager's reflective
permissions, which allows it to access the private members of the
class, are granted to Hibernate Validator, a potential privilege
escalation can occur. By allowing the calling code to access those
private members without the permission an attacker may be able to
validate an invalid instance and access the private member value via
ConstraintViolation#getInvalidValue(). (CVE-2017-7536)

The CVE-2017-2582 issue was discovered by Hynek Mlnarik (Red Hat) and
the CVE-2017-7536 issue was discovered by Gunnar Morling (Red Hat).
