    Several vulnerabilities in wordpress, a web blogging tool, have been
    fixed.
    
    CVE-2019-17669
    
        Server Side Request Forgery (SSRF) vulnerability because URL
        validation does not consider the interpretation of a name as a
        series of hex characters.
    
    CVE-2019-17670
    
       Server Side Request Forgery (SSRF) vulnerability was reported in
       wp_validate_redirect(). Normalize the path when validating the
       location for relative URLs.
    
    CVE-2019-17671
    
       Unauthenticated viewing of certain content (private or draft posts)
       is possible because the static query property is mishandled.
    
    CVE-2019-17675
    
        Wordpress does not properly consider type confusion during
        validation of the referer in the admin pages. This vulnerability
        affects the check_admin_referer() WordPress function.
    
    For Debian 8 "Jessie", these problems have been fixed in version
    4.1.28+dfsg-0+deb8u1.
    
    We recommend that you upgrade your wordpress packages.
