RHSA-2016:0008: Moderate: openssl security update

First published: Thu Jan 07 2016(Updated: )

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)<br>and Transport Layer Security (TLS v1) protocols, as well as a<br>full-strength, general purpose cryptography library.<br>A flaw was found in the way TLS 1.2 could use the MD5 hash function for<br>signing ServerKeyExchange and Client Authentication packets during a TLS<br>handshake. A man-in-the-middle attacker able to force a TLS connection to<br>use the MD5 hash function could use this flaw to conduct collision attacks<br>to impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575)<br>All openssl users are advised to upgrade to these updated packages, which<br>contain a backported patch to correct this issue. For the update to take<br>effect, all services linked to the OpenSSL library must be restarted, or<br>the system rebooted.<br>
