                   Red Hat Security Advisory

Synopsis:          Important: Red Hat JBoss Enterprise Application Platform 6.4.16 natives update
Advisory ID:       RHSA-2017:1658-01
Product:           Red Hat JBoss Enterprise Application Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:1658
Issue date:        2017-06-28
CVE Names:         CVE-2016-2177 CVE-2016-2178 CVE-2016-6304 
                   CVE-2016-8610 
=====================================================================

1. Summary:

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

2. Relevant releases/architectures:

Red Hat JBoss Enterprise Application Platform 6.4 for RHEL 6 Server - i386, ppc64, x86_64
Red Hat JBoss Enterprise Application Platform 6.4 for RHEL 7 Server - ppc64, x86_64

3. Description:

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

This release includes bug fixes as well as a new release of OpenSSL. For
further information, see the knowledge base article linked to in the
References section. All users of Red Hat JBoss Enterprise Application
Platform 6.4 on Red Hat Enterprise Linux 7 are advised to upgrade to these
updated packages. The JBoss server process must be restarted for the update
to take effect.

Security Fix(es):

* A memory leak flaw was found in the way OpenSSL handled TLS status
request extension data during session renegotiation. A remote attacker
could cause a TLS server using OpenSSL to consume an excessive amount of
memory and, possibly, exit unexpectedly after exhausting all available
memory, if it enabled OCSP stapling support. (CVE-2016-6304)

* It was discovered that OpenSSL did not always use constant time
operations when computing Digital Signature Algorithm (DSA) signatures. A
local attacker could possibly use this flaw to obtain a private DSA key
belonging to another user or service running on the same system.
(CVE-2016-2178)

* A denial of service flaw was found in the way the TLS/SSL protocol
defined processing of ALERT packets during a connection handshake. A remote
attacker could use this flaw to make a TLS/SSL server consume an excessive
amount of CPU and fail to accept connections form other clients.
(CVE-2016-8610)

* Multiple integer overflow flaws were found in the way OpenSSL performed
pointer arithmetic. A remote attacker could possibly use these flaws to
cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2016-2177)

Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304
and Shi Lei (Gear Team of Qihoo 360 Inc.) for reporting CVE-2016-8610.
Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.) as the original
reporter of CVE-2016-6304.

4. Solution:

Before applying this update, back up your existing Red Hat JBoss Enterprise
Application Platform installation and deployed applications.

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the OpenSSL library
must be restarted, or the system rebooted. After installing the updated
packages, the httpd daemon will be restarted automatically.

5. Bugs fixed (https://bugzilla.redhat.com/):

1341705 - CVE-2016-2177 openssl: Possible integer overflow vulnerabilities in codebase
1343400 - CVE-2016-2178 openssl: Non-constant time codepath followed for certain operations in DSA implementation
1377600 - CVE-2016-6304 openssl: OCSP Status Request extension unbounded memory growth
1384743 - CVE-2016-8610 SSL/TLS: Malformed plain-text ALERT packets could cause remote DoS
