An update for openssl is now available for Red Hat Enterprise Linux 5.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.
Security Fix(es) :
Red Hat would like to thank the OpenSSL project for reporting this issue. Upstream acknowledges Huzaifa Sidhpurwala (Red Hat), Hanno Bock, and David Benjamin (Google) as the original reporters.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL)
and Transport Layer Security (TLS) protocols, as well as a
full-strength general-purpose cryptography library.
Security Fix(es) :
* A flaw was found in the way OpenSSL encoded certain ASN.1 data
structures. An attacker could use this flaw to create a specially
crafted certificate which, when verified or re-encoded by OpenSSL,
could cause it to crash, or execute arbitrary code using the
permissions of the user running an application compiled against the
OpenSSL library. (CVE-2016-2108)
