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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
