Red Hat Security Advisory

Synopsis: Moderate: openssl security update
Advisory ID: RHSA-2015:2616-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2616.html
Issue date: 2015-12-14
CVE Names: CVE-2015-3195
=====================================================================

1. Summary:

Updated openssl packages that fix one security issue are now available
for Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, x86_64

3. Description:

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 memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and
CMS data. A remote attacker could use this flaw to cause an application
that parses PKCS#7 or CMS data from untrusted sources to use an excessive
amount of memory and possibly crash. (CVE-2015-3195)

All openssl users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For the update to take
effect, all services linked to the OpenSSL library must be restarted, or
the system rebooted.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
