SCA: security update for dompdf/dompdf (GHSA-577p-7j7h-2jgf)

critical Tenable Cloud Security Plugin ID 410645

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - DomPDF before version 2.0.0 is vulnerable to PHAR deserialization due to a lack of checking on the
 protocol before passing it into the file_get_contents() function. An attacker who can upload files of any
 type to the server can pass in the phar:// protocol to unserialize the uploaded file and instantiate
 arbitrary PHP objects. This can lead to remote code execution, especially when DOMPdf is used with
 frameworks with documented POP chains like Laravel or vulnerable developer code. (CVE-2021-3838)
