-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Web Server 2.1.1 security update on RHEL 6 Advisory ID: RHSA-2016:1649-01 Product: Red Hat JBoss Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-1649.html Issue date: 2016-08-22 CVE Names: CVE-2016-2105 CVE-2016-2106 CVE-2016-3110 CVE-2016-5387 ===================================================================== 1. Summary: An update is now available for Red Hat JBoss Enterprise Web Server 2.1 for RHEL 6. 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 Web Server 2 for RHEL 6 Server - i386, noarch, x86_64 3. Description: 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 serves as a replacement for Red Hat JBoss Web Server 2.1.0, and includes several bug fixes. Refer to the Red Hat JBoss Web Server 2.1.1 Release Notes, linked to in the References section, for information on the most significant of these changes. All users of Red Hat JBoss Web Server 2.1.0 on Red Hat Enterprise Linux 6 are advised to upgrade to Red Hat JBoss Web Server 2.1.1. The JBoss server process must be restarted for this update to take effect. Security Fix(es): * It was discovered that httpd used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request. (CVE-2016-5387) * An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncodeUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2105) * An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncryptUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2106) * It was discovered that it is possible to remotely Segfault Apache http server with a specially crafted string sent to the mod_cluster via service messages (MCMP). (CVE-2016-3110) Red Hat would like to thank Scott Geary (VendHQ) for reporting CVE-2016-5387; the OpenSSL project for reporting CVE-2016-2105 and CVE-2016-2106; and Michal Karm Babacek for reporting CVE-2016-3110. Upstream acknowledges Guido Vranken as the original reporter of CVE-2016-2105 and CVE-2016-2106. 4. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). 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. Refer to the Red Hat JBoss Enterprise Web Server 2.1.1 Release Notes for a list of non security related fixes. 5.
