Red Hat: RHSA-2014:0015-01 Important: OpenSSL Crash and Security Fix

red hat
Calendar Grey January 8, 2014
Dist Redhat Esm H88
Red Hat updates address OpenSSL vulnerabilities to boost security. It's crucial to upgrade now for system stability.
Updated openssl packages that fix three security issues are now available for Red Hat Enterprise Linux 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/site/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 flaw was found in the way OpenSSL determined which hashing algorithm to use when TLS protocol version 1.2 was enabled. This could possibly cause OpenSSL to use an incorrect hashing algorithm, leading to a crash of an application using the library. (CVE-2013-6449)
It was discovered that the Datagram Transport Layer Security (DTLS) protocol implementation in OpenSSL did not properly maintain encryption and digest contexts during renegotiation. A lost or discarded renegotiation handshake packet could cause a DTLS client or server using OpenSSL to crash. (CVE-2013-6450)
A NULL pointer dereference flaw was found in the way OpenSSL handled TLS/SSL protocol handshake packets. A specially crafted handshake packet could cause a TLS/SSL client using OpenSSL to crash. (CVE-2013-4353)
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.
