(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.
  
Impact :

    By feeding specially crafted file names to GraphicsMagick an
    attacker can crash the program and possibly execute arbitrary code with
    the privileges of the user running GraphicsMagick.
  
Workaround :

    There is no known workaround at this time."
