Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform various Cross-Side Scripting (XSS) and Cross-Site Request Forgery (CSRF) attacks, create files on the server, disclose private information, create open redirects, poison cache, and bypass authorization access and input sanitation.

Solution

Upgrade the wordpress packages.

For the oldstable distribution (stretch), these problems have been fixed in version 4.7.5+dfsg-2+deb9u6.

For the stable distribution (buster), these problems have been fixed in version 5.0.4+dfsg1-1+deb10u2.
