"An update is now available for JBoss Core Services on 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.

Red Hat JBoss Core Services is a set of supplementary software for Red
Hat JBoss middleware products. This software, such as Apache HTTP
Server, is common to multiple JBoss middleware products, and is
packaged under Red Hat JBoss Core Services to allow for faster
distribution of updates, and for a more consistent update experience.

This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.23
Service Pack 2 serves as an update for Red Hat JBoss Core Services
Apache HTTP Server 2.4.23 Service Pack 1, and includes bug fixes,
which are documented in the Release Notes document linked to in the
References.

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)

* It was discovered that in httpd 2.4, the internal API function
ap_some_auth_required() could incorrectly indicate that a request was
authenticated even when no authentication was used. An httpd module
using this API function could consequently allow access that should
have been denied. (CVE-2015-3185)

* 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)

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