1. Summary:

An update for eap7-jboss-ec2-eap is now available for Red Hat JBoss
Enterprise Application Platform 7.0 for Red Hat Enterprise Linux 6 and Red
Hat JBoss Enterprise Application Platform 7.0 for Red Hat Enterprise Linux

Red Hat Product Security has rated this update as having a security impact
of Important. 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.

2. Relevant releases/architectures:

Red Hat JBoss Enterprise Application Platform 7.0 for RHEL 6 Server – noarch
Red Hat JBoss Enterprise Application Platform 7.0 for RHEL 7 Server – noarch

3. Description:

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().

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).
