Checking Ubuntu Servers for openssh and openssl vulnerable keys

  1. Update openssh and openssl packages
    # apt-get update
    # apt-get install openssh openssl
  2. Install openssh-blacklist and openssl-blacklist
    # apt-get install openssh-blacklist openssl-blacklist
  3. Check all ssh compromised keys via:
    # ssh-vulnkeys -a
  4. Check all ssl keys and certificates via:
    # openssl-vulnkeys *.key *.pem

    Note: Plesk specific ssl certs are stored at "/opt/psa/var/certificates/"
