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)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-0426 advisory.

    - fix for CVE-2012-0884 - MMA weakness in CMS and PKCS#7 code (#802725)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated openssl packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

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.

This minor update from upstream fixes two security vulnerabilities with moderate and low impact.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
