Details

Neel Mehta discovered that OpenSSL incorrectly handled memory in the TLS
heartbeat extension. An attacker could use this issue to obtain up to 64k
of memory contents from the client or server, possibly leading to the
disclosure of private keys and other sensitive information. (CVE-2014-0160)

Yuval Yarom and Naomi Benger discovered that OpenSSL incorrectly handled
timing during swap operations in the Montgomery ladder implementation. An
attacker could use this issue to perform side-channel attacks and possibly
recover ECDSA nonces. (CVE-2014-0076)
