This is part of a group of similar vulnerabilities related to cmap pickle files in pdfminer. https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2025-286b1c8479 included a backport of upstream’s change to switch cmaps from pickle to json, which will have addressed all issues related to pickle files.
