  "summary": "CVE-2023-24813 is fixed in php-dompdf on 1 platform by DEBIAN-CVE-2023-24813 (version 2.0.3\u002Bdfsg-1), released February 7, 2023. It is not reported as exploited. Patch Radar priority: Urgent.",
  "title": "php-dompdf: Dompdf is an HTML to PDF converter written in php",
  "description": "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 \u0060image\u0060 tags and respects \u0060xlink:href\u0060 even if \u0060href\u0060 is specified. However, php-svg-lib, which is later used to parse the svg file, parses the href attribute. Since \u0060href\u0060 is respected if both \u0060xlink:href\u0060 and \u0060href\u0060 is specified, it\u0027s possible to bypass the protection on the Dompdf side by providing an empty \u0060xlink:href\u0060 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 \u006095009ea98\u0060 which has been included in release version 2.0.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.",
