A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure Real-time Transport Protocol (SRTP) extension data. A remote attacker could send multiple specially crafted handshake messages to exhaust all available memory of an SSL/TLS or DTLS server. (CVE-2014-3513)
A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. (CVE-2014-3567)
When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be
configured to send them. (CVE-2014-3568)
Run yum update openssl to update your system. Note that you may need to run yum clean all first.
