Ubuntu Security Notice 3840-1 - 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. 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. Various other issues were also addressed.
