SCA: security update for dompdf/dompdf (GHSA-56gj-mvh6-rp75)

critical Tenable Self-Hosted Container Security Plugin ID 410626

Description

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

 - Dompdf is an HTML to PDF converter written in php. Due to the difference in the attribute parser of Dompdf
 and php-svg-lib, an attacker can still call arbitrary URLs with arbitrary protocols. Dompdf parses the
 href attribute of `image` tags and respects `xlink:href` even if `href` is specified. However, php-svg-
 lib, which is later used to parse the svg file, parses the href attribute. Since `href` is respected if
 both `xlink:href` and `href` is specified, it's possible to bypass the protection on the Dompdf side by
 providing an empty `xlink:href` attribute. An attacker can exploit the vulnerability to call arbitrary
 URLs with arbitrary protocols if they provide an SVG file to the Dompdf. In PHP versions before 8.0.0, it
 leads to arbitrary unserialize, which will lead, at the very least, to arbitrary file deletion and might
 lead to remote code execution, depending on available classes. This vulnerability has been addressed in
 commit `95009ea98` which has been included in release version 2.0.3. Users are advised to upgrade. There
 are no known workarounds for this vulnerability. (CVE-2023-24813)
