1. Summary:

An update is now available for Red Hat JBoss Enterprise Application
Platform.

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. Description:

Red Hat JBoss Enterprise Application Platform is a platform for Java
applications based on the JBoss Application Server.

This release of Red Hat JBoss Enterprise Application Platform 7.0.7 serves
as a replacement for Red Hat JBoss Enterprise Application Platform 7.0.6,
and includes bug fixes and enhancements, which are documented in the
Release Notes document linked to in the References.

Security Fix(es):

* A deserialization flaw was discovered in jackson-databind which could
allow an unauthenticated user to perform code execution by sending
maliciously crafted input to the readValue method of the ObjectMapper.
(CVE-2017-7525)

* It was found that use of a JMS ObjectMessage does not safely handle
user-supplied data when deserializing objects. A remote attacker could use
this flaw to execute arbitrary code with the permissions of the application
using the JMS ObjectMessage. (CVE-2016-4978)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting
CVE-2017-7525.
