1. Summary:

An update is now available for Red Hat JBoss Enterprise Application
Platform 6.4.

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 6.4.17 serves
as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.16,
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 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 discovered in the error page mechanism in Tomcat's
DefaultServlet implementation. A crafted HTTP request could cause undesired
side effects, possibly including the removal or replacement of the custom
error page. (CVE-2017-5664)

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

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting
