"An invalid free flaw was found in the way OpenSSL handled certain DTLS
handshake messages. A malicious DTLS client or server could cause a
DTLS server or client using OpenSSL to crash or, potentially, execute
arbitrary code. (CVE-2014-8176)

A flaw was found in the way the OpenSSL packages shipped with
Scientific Linux 6 and 7 performed locking in the ssleay_rand_bytes()
function. This issue could possibly cause a multi-threaded application
using OpenSSL to perform an out-of-bounds read and crash.
(CVE-2015-3216)

An out-of-bounds read flaw was found in the X509_cmp_time() function
of OpenSSL. A specially crafted X.509 certificate or a Certificate
Revocation List (CRL) could possibly cause a TLS/SSL server or client
using OpenSSL to crash. (CVE-2015-1789)

A race condition was found in the session handling code of OpenSSL.
This issue could possibly cause a multi-threaded TLS/SSL client using
OpenSSL to double free session ticket data and crash. (CVE-2015-1791)

A flaw was found in the way OpenSSL handled Cryptographic Message
Syntax (CMS) messages. A CMS message with an unknown hash function
identifier could cause an application using OpenSSL to enter an
infinite loop. (CVE-2015-1792)

A NULL pointer dereference was found in the way OpenSSL handled
certain PKCS#7 inputs. A specially crafted PKCS#7 input with missing
EncryptedContent data could cause an application using OpenSSL to
crash. (CVE-2015-1790)

For the update to take effect, all services linked to the OpenSSL
library must be restarted, or the system rebooted."
