"An update for jboss-ec2-eap is now available for Red Hat JBoss
Enterprise Application Platform 6.4 for Red Hat Enterprise Linux 6.

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.

The 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 jboss-ec2-eap package has been updated to ensure
compatibility with Red Hat JBoss Enterprise Application Platform
6.4.17.

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
CVE-2017-7525."
