New! Plugin Severity Now Using CVSS v3

Description

OpenSSL versions 1.0.1 earlier than 1.0.1g contain the following vulnerabilities:

- Out-of-bounds read flaw that can be triggered through TLS heartbeat extension packets to disclose up to 64kB of memory containing sensitive information, possibly including secret keys. (CVE-2014-0160)

- Improperly implemented Elliptic Curve Digital Signature Algorithm (ECDSA) could allow nonce disclosure via the 'FLUSH+RELOAD' cache side-channel attack. (CVE-2014-0076)
