EPEL 9 has mupdf-1.21.1. The POC leads to ``` ... warning: cannot load object (3 0 R) into cache warning: invalid indirect reference in dict error: invalid key in dict warning: cannot load object (3 0 R) into cache warning: invalid indirect reference in dict error: invalid key in dict warning: cannot load object (3 0 R) into cache error: not a dict (null) ``` rather than `Segmentation fault` (with the affected versions), so EPEL 9 apears to be unaffected.
