"An update is now available for Red Hat JBoss Web Server 3.1 for RHEL 6
and Red Hat JBoss Web Server 3.1 for RHEL 7.

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.

Red Hat JBoss Web Server is a fully integrated and certified set of
components for hosting Java web applications. It is comprised of the
Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat
Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and
the Tomcat Native library.

This release of Red Hat JBoss Web Server 3.1 Service Pack 1 serves as
a replacement for Red Hat JBoss Web Server 3.1, and includes bug
fixes, 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 tomcat's handling of pipelined
requests when 'Sendfile' was used. If sendfile processing completed
quickly, it was possible for the Processor to be added to the
processor cache twice. This could lead to invalid responses or
information disclosure. (CVE-2017-5647)

* 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 vulnerability was discovered in tomcat. When running an untrusted
application under a SecurityManager it was possible, under some
circumstances, for that application to retain references to the
request or response objects and thereby access and/or modify
information associated with another web application. (CVE-2017-5648)"
