Debian Bug : 942459
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.
