Description

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)
