How to fix?

Upgrade Debian:unstable php-dompdf to version 0.6.1+dfsg-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-dompdf package and not the php-dompdf package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

dompdf.php in dompdf before 0.6.1, when DOMPDF_ENABLE_PHP is enabled, allows context-dependent attackers to bypass chroot protections and read arbitrary files via a PHP protocol and wrappers in the input_file parameter, as demonstrated by a php://filter/read=convert.base64-encode/resource in the input_file parameter.
