Multiple security issues have been fixed in OpenSSL: The TLS 1.2 support was susceptible to denial of service and retransmission of DTLS messages was fixed. In addition this update disables the insecure Dual_EC_DRBG algorithm (which was unused anyway, see http://marc.info/?l=openssl-announce&m=138747119822324&w=2 for further information) and no longer uses the RdRand feature available on some Intel CPUs as a sole source of entropy unless explicitly requested.
