CVE ID         : CVE-2019-8942 CVE-2019-9787
Debian Bug     : 924546


Simon Scannell of Ripstech Technologies discovered multiple
vulnerabilities in wordpress, a web blogging manager.

CVE-2019-8942

    remote code execution in wordpress because an _wp_attached_file Post
    Meta entry can be changed to an arbitrary string, such as one ending
    with a .jpg?file.php substring. An attacker with author privileges
    can execute arbitrary code by uploading a crafted image containing
    PHP code in the Exif metadata.

CVE-2019-9787

    wordpress does not properly filter comment content, leading to
    Remote Code Execution by unauthenticated users in a default
    configuration. This occurs because CSRF protection is mishandled,
    and because Search Engine Optimization of A elements is performed
    incorrectly, leading to XSS. The XSS results in administrative
    access.

For Debian 8 "Jessie", these problems have been fixed in version
4.1.26+dfsg-1+deb8u1.

We recommend that you upgrade your wordpress packages.
