Summary
openssl vulnerabilities
Details

David Benjamin discovered that OpenSSL did not correctly prevent buggy applications that ignore handshake errors from subsequently calling certain functions. (CVE-2017-3737)

It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery multiplication procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. (CVE-2017-3738)
