    - An improper handing of overflow in the UTF-8 decoder
      with supplementary characters can lead to an infinite
      loop in the decoder causing a Denial of Service.
      (CVE-2018-1336)

    - When using an OCSP responder Apache Tomcat Native
      1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 did not correctly
      handle invalid responses. This allowed for revoked client
      certificates to be incorrectly identified. It was therefore
      possible for users to authenticate with revoked certificates
      when using mutual TLS.(CVE-2018-8019)
      
    - Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 has
      a flaw that does not properly check OCSP pre-produced responses,
      which are lists (multiple entries) of certificate statuses.
      (CVE-2018-8020)

    - The host name verification when using TLS with the
      WebSocket client was missing. It is now enabled by
      default. (CVE-2018-8034)

issues :

CVE-2017-15698: Fixed an improper handling of fields with more than
127 bytes which could allow invalid client certificates to be accepted
(bsc#1078679).

CVE-2018-8019: When using an OCSP responder did not correctly handle
invalid responses. This allowed for revoked client certificates to be
incorrectly identified. It was therefore possible for users to
authenticate with revoked certificates when using mutual TLS
(bsc#1103348).

CVE-2018-8020: Did not properly check OCSP pre-produced responses.
Revoked client certificates may have not been properly identified,
allowing for users to authenticate with revoked certificates to
connections that require mutual TLS (bsc#1103347).

Red Hat Product Security has rated this release 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 4 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) :

* tomcat: Insecure defaults in CORS filter enable
'supportsCredentials' for all origins (CVE-2018-8014)

* tomcat-native: Mishandled OCSP invalid response (CVE-2018-8019)

* tomcat-native: Mishandled OCSP responses can allow clients to
authenticate with revoked certificates (CVE-2018-8020)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.

The following packages have been upgraded to a newer upstream 
version :

* OpenSSL (1.0.2n)

* APR (1.6.3)

CVE-2018-8019 and CVE-2018-8020 were discovered by Coty Sutherland
(Red Hat)."

"When using an OCSP responder Tomcat Native did not correctly handle
invalid responses. This allowed for revoked client certificates to be
incorrectly identified. It was therefore possible for users to
authenticate with revoked certificates when using mutual TLS. Users
not using OCSP checks are not affected by this vulnerability.

For Debian 8 'Jessie', these problems have been fixed in version
1.1.32~repack-2+deb8u2.

We recommend that you upgrade your tomcat-native packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
