Debian Stretch: DSA-4321-1 Moderate: GraphicsMagick Denial Of Service

Several vulnerabilities have been discovered in GraphicsMagick, a set of
command-line applications to manipulate image files, which could result
in denial of service or the execution of arbitrary code if malformed
image files are processed.

For the stable distribution (stretch), these problems have been fixed in
version 1.3.30+hg15796-1~deb9u1.

We recommend that you upgrade your graphicsmagick packages.
