Debian Bug     : 973562

There were several vulnerabilites reported against wordpress,
as follows:

CVE-2020-28032

    WordPress before 4.7.19 mishandles deserialization requests in
    wp-includes/Requests/Utility/FilteredIterator.php.

CVE-2020-28033

    WordPress before 4.7.19 mishandles embeds from disabled sites
    on a multisite network, as demonstrated by allowing a spam
    embed.

CVE-2020-28034

    WordPress before 4.7.19 allows XSS associated with global
    variables.

CVE-2020-28035

    WordPress before 4.7.19 allows attackers to gain privileges via
    XML-RPC.

CVE-2020-28036

    wp-includes/class-wp-xmlrpc-server.php in WordPress before
    4.7.19 allows attackers to gain privileges by using XML-RPC to
    comment on a post.

CVE-2020-28037

    is_blog_installed in wp-includes/functions.php in WordPress
    before 4.7.19 improperly determines whether WordPress is
    already installed, which might allow an attacker to perform
    a new installation, leading to remote code execution (as well
    as a denial of service for the old installation).

CVE-2020-28038

    WordPress before 4.7.19 allows stored XSS via post slugs.

CVE-2020-28039

    is_protected_meta in wp-includes/meta.php in WordPress before
    4.7.19 allows arbitrary file deletion because it does not
    properly determine whether a meta key is considered protected.

CVE-2020-28040

    WordPress before 4.7.19 allows CSRF attacks that change a
    theme's background image.

For Debian 9 stretch, these problems have been fixed in version
4.7.19+dfsg-1+deb9u1.

We recommend that you upgrade your wordpress packages.
