Dompdf: Chroot Validation Bypass

Summary The chroot check for local files uses a prefix string check to enforce chroot boundaries. The simple string comparison it performs allows paths like /var/www/rootsecret/file.html when chroot is /var/www/root. This allows attacker-controlled document paths/resources to bypass intended loca...
