Summary
openssl, openssl1.0 vulnerabilities
Details

Samuel Weiser discovered that OpenSSL incorrectly handled DSA signing. An attacker could possibly use this issue to perform a timing side-channel attack and recover private DSA keys. (CVE-2018-0734)

Samuel Weiser discovered that OpenSSL incorrectly handled ECDSA signing. An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys. This issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-0735)

Billy Bob Brumley, Cesar Pereida Garcia, Sohaib ul Hassan, Nicola Tuveri, and Alejandro Cabrera Aldaya discovered that Simultaneous Multithreading (SMT) architectures are vulnerable to side-channel leakage. This issue is known as "PortSmash". An attacker could possibly use this issue to perform a timing side-channel attack and recover private keys. (CVE-2018-5407)
