GraphicsMagick: Format string vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200602-13
(GraphicsMagick: Format string vulnerability)

The SetImageInfo function was found vulnerable to a format string
mishandling. Daniel Kobras discovered that the handling of "%"-escaped
sequences in filenames passed to the function is inadequate in
ImageMagick GLSA 200602-06 and the same vulnerability exists in
GraphicsMagick.

attacker can crash the program and possibly execute arbitrary code with
the rights of the user running GraphicsMagick.

Workaround

There is no known workaround at this time.
