Reading the upstream bug report, there seem to be no solution in sight any time soon. Perhaps it would be better if mat simply reported a failure and refused to process the input if it find embedded parts it can't strip? It would be better than pretending to succeed. > I wonder if similar bugs happen with other recursive formats, like an > OpenDocument text embedding an image or embedding a pdf embedding an > image or a zip file containing a zip file containing a .odt file > containing an pdf containing an image??? No idea, but it would be useful to check. :) Did you ever get a CVE for this issue? I did not find one when I followed the mailing list thread, but might have missed it. -- Happy hacking Petter Reinholdtsen
