Description


Updated openssl packages that fix three security issues are now available
for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

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 derefernce 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.

Am I vulnerable?

The constraints below list the versions that this vulnerability is patched in, and versions that are unaffected. If a patch is ready but unrealeased, then it is pending.

Or, you can just let us figure it out for you! Appcanary continously monitor your installed packages, and tell you if any of them are vulnerable.
