Test ID:1.3.6.1.4.1.25623.1.0.882340
Category:CentOS Local Security Checks
Title:CentOS Update for openssl CESA-2015:2617 centos6
Summary:Check the version of openssl
Description:Summary:
Check the version of openssl

Vulnerability Insight:
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 NULL pointer dereference flaw was found in the way OpenSSL verified
signatures using the RSA PSS algorithm. A remote attacked could possibly
use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server
using OpenSSL if it enabled client authentication. (CVE-2015-3194)

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)

A race condition flaw, leading to a double free, was found in the way
OpenSSL handled pre-shared key (PSK) identify hints. A remote attacker
could use this flaw to crash a multi-threaded SSL/TLS client using
OpenSSL. (CVE-2015-3196)

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.

Affected Software/OS:
openssl on CentOS 6

Solution:
Please install the updated packages.
