This error is because of the vulnerability. This allows remote execution of code using image formats. So, some Linux distributions by default, the ImageMagic conversion is turned-off for some image file extensions. For example, I frequently convert .jpeg/.jpg to .eps. But, every time, I got an error. Here is the way how to solve it [Remember to change back the settings after converting the file in order to avoid vulnerability].
You have to change the policy.xml file in the installed ImageMagic package.
To do that, USE:
sudo vim /etc/ImageMagick-6/policy.xml
<policy domain="coder" rights="read | write" pattern="EPS" />
and save. Note that you should change "none" to "read | write" and then save.
Once you did this modification, you can convert using "convert" command.
Now, TRY:
convert figure.jpg figure.eps
After conversion, you may change back the line as it was before (to avoid vulnerability) which is very important.
