"An update is now available for Red Hat JBoss Enterprise Application
Platform 6.4 for RHEL 6 and Red Hat JBoss Enterprise Application
Platform 6.4 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.

[Updated 21st November 2017] Previously, this erratum was marked as a
replacement of the JBoss Enterprise Application Platform 6.4.16
Natives. This was incorrect; the erratum is an update, not a
replacement. The erratum text has been modified to reflect this.

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

This release provides an update to httpd and OpenSSL. The updates are
documented in the Release Notes document linked to in the References.

The httpd packages provide the Apache HTTP Server, a powerful,
efficient, and extensible web server.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL)
and Transport Layer Security (TLS) protocols, as well as a
full-strength general-purpose cryptography library.

This release of JBoss Enterprise Application Platform 6.4.18 Natives
serves as an update to the JBoss Enterprise Application Platform
6.4.16 Natives and includes bug fixes which are documented in the
Release Notes document linked to in the References.

All users of Red Hat JBoss Enterprise Application Platform 6.4 Natives
are advised to upgrade to these updated packages.

Security Fix(es) :

* It was discovered that the httpd's mod_auth_digest module did not
properly initialize memory before using it when processing certain
headers related to digest authentication. A remote attacker could
possibly use this flaw to disclose potentially sensitive information
or cause httpd child process to crash by sending specially crafted
requests to a server. (CVE-2017-9788)

* A flaw was found in the way the DES/3DES cipher was used as part of
the TLS /SSL protocol. A man-in-the-middle attacker could use this
flaw to recover some plaintext data by capturing large amounts of
encrypted traffic between TLS/SSL server and client if the
communication used a DES/3DES based ciphersuite. (CVE-2016-2183)

* A use-after-free flaw was found in the way httpd handled invalid and
previously unregistered HTTP methods specified in the Limit directive
used in an .htaccess file. A remote attacker could possibly use this
flaw to disclose portions of the server memory, or cause httpd child
process to crash. (CVE-2017-9798)

Red Hat would like to thank OpenVPN for reporting CVE-2016-2183 and
Hanno Bock for reporting CVE-2017-9798. Upstream acknowledges
Karthikeyan Bhargavan (Inria) and Gaetan Leurent (Inria) as the
original reporters of CVE-2016-2183.

Bug Fix(es) :

* CRL checking of very large CRLs fails with OpenSSL 1.0.2
(BZ#1508880)

* mod_cluster segfaults in process_info() due to wrongly generated
assembler instruction movslq (BZ#1508884)

* Corruption in nodestatsmem in multiple core dumps but in different
functions of each core dump. (BZ#1508885)"
