"The version of AgileBits 1Password installed on the remote Windows
host is equal or prior to 6.3.3. It is, therefore, affected by
multiple vulnerabilities :

  - A security weakness exists in the internal web browser
    in which the default protocol that is used is set to
    HTTP. If a user visits a website without specifying the
    full URL, the more secure HTTPS protocol will not be
    used even if it is available. A man-in-the-middle
    attacker can exploit this to disclose sensitive
    information. (SIK-2016-039)

  - A security weakness exists in the database of the
    password manager due to lack of encryption for titles
    and URLs. An attacker who is able to obtain a copy of
    the encrypted database can exploit this to disclose the
    websites for which the user has stored credentials
    without having to break the cryptography. (SIK-2016-040)

  - A security weakness exists in the password manager due
    to sending the target domain to the vendor's web server
    in order to obtain from a server-side cache an icon that
    represents the respective target website. This issue
    allows the vendor to track all the sites for which the
    user has created database entries. (SIK-2016-042)");
