Details

Keegan Ryan discovered that OpenSSL incorrectly handled ECDSA key
generation. An attacker could possibly use this issue to perform a
cache-timing attack and recover private ECDSA keys. (CVE-2018-0495)

Guido Vranken discovered that OpenSSL incorrectly handled very large prime
values during a key agreement. A remote attacker could possibly use this
issue to consume resources, leading to a denial of service. (CVE-2018-0732)

Alejandro Cabrera Aldaya, Billy Brumley, Cesar Pereida Garcia and Luis
Manuel Alvarez Tapia discovered that OpenSSL incorrectly handled RSA key
generation. An attacker could possibly use this issue to perform a
cache-timing attack and recover private RSA keys. (CVE-2018-0737)
