Cause

After an ImageMagick version upgrade, the ImageMagick policy does not allow working with the file.

Solution

Edit the ImageMagick policy.xml file and comment out the bottom policy rules that are affecting your file.

Or maybe (depending on your Linux distro and version):

The file before:

...
<policy domain="coder" rights="none" pattern="PS" />
<policy domain="coder" rights="none" pattern="EPS" />
<policy domain="coder" rights="none" pattern="PDF" />
<policy domain="coder" rights="none" pattern="XPS" />
...

The file after:

<policy domain="coder" rights="none" pattern="PS" />
<policy domain="coder" rights="none" pattern="EPS" />
<policy domain="coder" rights="read|write" pattern="PDF" />
<policy domain="coder" rights="none" pattern="XPS" />
