Cause

After some ImageMagick version upgrade the Imagemagick policy does not authorize working with the file.

Solution

Edit the ImageMagick policy.xml file and comment the bottom policy rules what is 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" />
