Public bug reported: This security updated https://usn.ubuntu.com/3785-1/ added the following to /etc/ImageMagick-6/policy.xml
<!-- disable ghostscript format types --> <policy domain="coder" rights="none" pattern="PS" /> <policy domain="coder" rights="none" pattern="EPI" /> <policy domain="coder" rights="none" pattern="PDF" /> <policy domain="coder" rights="none" pattern="XPS" /> This prevents from working with PDF, e.g. `convert file.pdf file.png`. It is a very common use case and is a suggested way to convert PDF to image on many websites, including ask.ubuntu.com I had to remove/comment those lines from /etc/ImageMagick-6/policy.xml to allow ImageMagick to work with PDF, otherwise it was: $ convert test1.pdf test1.png convert-im6.q16: not authorized `test1.pdf' @ error/constitute.c/ReadImage/412. convert-im6.q16: no images defined `test1.png' @ error/convert.c/ConvertImageCommand/3258. Can you please reenable GhostScript? I don't think that it is so insecure that so common use cases must be disabled, people, who do not read usn.ubuntu.com frequently, will not understand the error. Also, those security update disabled GhostScript on the fly; what if I used it on servers or for daily desktop tasks?
