Description of the vulnerability

Several vulnerabilities were announced in OpenSSL.

An attacker can force a read at an invalid address via Truncated Packet, in order to trigger a denial of service, or to obtain sensitive information. [severity:2/4; CVE-2017-3731]

An attacker can force a NULL pointer to be dereferenced via DHE/ECDHE Parameters, in order to trigger a denial of service. [severity:2/4; CVE-2017-3730]

An attacker can use a carry propagation error via BN_mod_exp(), in order to compute the private key. [severity:1/4; CVE-2017-3732]

An error occurs in the Broadwell-specific Montgomery Multiplication Procedure, but with no apparent impact. [severity:1/4; CVE-2016-7055]
