What is CVE-2025-46206?

A vulnerability exists in Artifex MuPDF versions 1.25.6 and 1.25.5 that permits a remote attacker to induce a denial of service condition. This flaw arises from the 'mutool clean' utility, which fails to properly handle crafted PDF files containing cyclic /Next references. When the 'strip_outline()' function processes these malicious files, it enters an infinite recursion loop, which may lead to excessive resource consumption and potential service disruption.
