RedHat: RHSA-2016-0305:01 Important: openssl security update
Summary
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.
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)
Note: This issue was addressed by disabling the SSLv2 protocol by default
when using the 'SSLv23' connection methods, and removing support for weak
SSLv2 cipher suites. For more information, refer to the knowledge base
article linked to in the References section.
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.
All openssl users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. For the update to take
effect, all services linked to the OpenSSL library must be restarted, or
the system rebooted.
Summary
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
