RHSA-2016:0490 - Important: Red Hat JBoss Enterprise Application Platform 6.4.6 OpenSSL security update
Synopsis
Important: Red Hat JBoss Enterprise Application Platform 6.4.6 OpenSSL security update
Type/Severity
Security Advisory Important
Topic
Updated packages that fix several OpenSSL security issues are available for Red Hat JBoss Enterprise Application Platform 6.4.6 for Microsoft Windows and Solaris.
Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Description
Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7.
A padding oracle flaw was found in the Secure Sockets Layer version 2.0 (SSLv2) protocol. An attacker can potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack is publicly referred to as DROWN. (CVE-2016-0800)
A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. (CVE-2015-0293)
A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that have been disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks. (CVE-2015-3197)
Red Hat would like to thank the OpenSSL project for reporting these issues. Upstream acknowledges Nimrod Aviram and Sebastian Schinzel as the original reporters of CVE-2016-0800 and CVE-2015-3197; and Sean Burford (Google) and Emilia Käsper (OpenSSL development team) as the original reporters of CVE-2015-0293.
All users of Red Hat JBoss Enterprise Application Platform 6.4 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.
Solution
Before applying this update, make sure all previously released errata relevant to your system have been applied, and back up your existing Red Hat JBoss Enterprise Application Platform installation (including all applications and configuration files).
