Description

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.
