It is, therefore, affected by multiple vulnerabilities :

  - An error exists that can allow the address bar to
    display incorrect locations due to certain combinations
    of navigation, reloads and redirects, which can aid in
    phishing attacks. (1018)

  - An error in JSON handling can allow cross-site
    scripting attacks. (1019)

  - An error exists related to handling double-click
    actions and new windows that can be used in cross-site
    scripting attacks. (1020)

  - An error exists in the handling of window focus that
    can allow keystrokes to be associated with non-visible
    windows. (1021)

  - An error in the handling of page loading can allow a
    malicious page to prevent the loading while showing an
    incorrect URL in the address bar. (1022)");
