Oracle Linux 7 : openssl (ELSA-2014-0679)

high Nessus Plugin ID 76729

Language:

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

From Red Hat Security Advisory 2014:0679 :

Updated openssl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 7.

The Red Hat Security Response Team has rated this update as having Important 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.

It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server.
(CVE-2014-0224)

Note: In order to exploit this flaw, both the server and the client must be using a vulnerable version of OpenSSL; the server must be using OpenSSL version 1.0.1 and above, and the client must be using any version of OpenSSL. For more information about this flaw, refer to: https://access.redhat.com/site/articles/904433

A buffer overflow flaw was found in the way OpenSSL handled invalid DTLS packet fragments. A remote attacker could possibly use this flaw to execute arbitrary code on a DTLS client or server. (CVE-2014-0195)

Multiple flaws were found in the way OpenSSL handled read and write buffers when the SSL_MODE_RELEASE_BUFFERS mode was enabled. A TLS/SSL client or server using OpenSSL could crash or unexpectedly drop connections when processing certain SSL traffic. (CVE-2010-5298, CVE-2014-0198)

A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash. (CVE-2014-0221)

A NULL pointer dereference flaw was found in the way OpenSSL performed anonymous Elliptic Curve Diffie Hellman (ECDH) key exchange. A specially crafted handshake packet could cause a TLS/SSL client that has the anonymous ECDH cipher suite enabled to crash. (CVE-2014-3470)

Red Hat would like to thank the OpenSSL project for reporting these issues. Upstream acknowledges KIKUCHI Masashi of Lepidum as the original reporter of CVE-2014-0224, Juri Aedla as the original reporter of CVE-2014-0195, Imre Rad of Search-Lab as the original reporter of CVE-2014-0221, and Felix Grobert and Ivan Fratric of Google as the original reporters of CVE-2014-3470.

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 (such as httpd and other SSL-enabled services) must be restarted or the system rebooted.

Solution

Update the affected openssl packages.
