-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== 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.
