Red Hat 6: RHSA-2012:0426-01 Moderate Bug Fix for OpenSSL Issues

Scroller Redhat
Ubuntu issues a significant release note concerning openssl, providing security patches for its versions 1.1 and 1.2.
Updated openssl packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 5 and 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258

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 NULL pointer dereference flaw was found in the way OpenSSL parsed Secure/Multipurpose Internet Mail Extensions (S/MIME) messages. An attacker could use this flaw to crash an application that uses OpenSSL to decrypt or verify S/MIME messages. (CVE-2012-1165)
A flaw was found in the PKCS#7 and Cryptographic Message Syntax (CMS) implementations in OpenSSL. An attacker could possibly use this flaw to perform a Bleichenbacher attack to decrypt an encrypted CMS, PKCS#7, or S/MIME message by sending a large number of chosen ciphertext messages to a service using OpenSSL and measuring error response times. (CVE-2012-0884)
This update also fixes a regression caused by the fix for CVE-2011-4619, released via RHSA-2012:0060 and RHSA-2012:0059, which caused Server Gated Cryptography (SGC) handshakes to fail.
All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.
