SCA: security update for dompdf/dompdf (GHSA-3qx2-6f78-w2j2)

high Tenable Cloud Security Plugin ID 409668

Description

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

 - Dompdf is an HTML to PDF converter for PHP. When parsing SVG images Dompdf performs an initial validation
 to ensure that paths within the SVG are allowed. One of the validations is that the SVG document does not
 reference itself. However, prior to version 2.0.4, a recursive chained using two or more SVG documents is
 not correctly validated. Depending on the system configuration and attack pattern this could exhaust the
 memory available to the executing process and/or to the server itself. php-svg-lib, when run in isolation,
 does not support SVG references for `image` elements. However, when used in combination with Dompdf, php-
 svg-lib will process SVG images referenced by an `image` element. Dompdf currently includes validation to
 prevent self-referential `image` references, but a chained reference is not checked. A malicious actor may
 thus trigger infinite recursion by chaining references between two or more SVG images. When Dompdf parses
 a malicious payload, it will crash due after exceeding the allowed execution time or memory usage. An
 attacker sending multiple request to a system can potentially cause resource exhaustion to the point that
 the system is unable to handle incoming request. Version 2.0.4 contains a fix for this issue.
