    Debian Bug     : 942459 962685
    Multiple vulnerabilities were discovered in Wordpress, a popular
    content management framework.
        WordPress has a Server Side Request Forgery (SSRF) vulnerability
        because Windows paths are mishandled during certain validation of
        relative URLs.
        Authenticated users with upload permissions (like authors) are
        able to inject JavaScript into some media file attachment pages in
        a certain way. This can lead to script execution in the context of
        a higher privileged user when the file is viewed by them.
        Due to an issue in wp_validate_redirect() and URL sanitization, an
        arbitrary external link can be crafted leading to unintended/open
        redirect when clicked.
        When uploading themes, the name of the theme folder can be crafted
        in a way that could lead to JavaScript execution in /wp-admin on
        the themes page.
        Misuse of the `set-screen-option` filter's return value allows
        arbitrary user meta fields to be saved. It does require an admin
        to install a plugin that would misuse the filter. Once installed,
        it can be leveraged by low privileged users.
    Additionally, this upload ensures latest comments can only be viewed
    from public posts, and fixes back the user activation procedure.
    For Debian 9 stretch, these problems have been fixed in version
    We recommend that you upgrade your wordpress packages.
