Debian: DSA-5288-1 Critical: GraphicsMagick Buffer Overflow Issue

It was discovered that a buffer overflow in GraphicsMagick, a collection
of image processing tools, could potentially result in the execution of
arbitrary code when processing a malformed MIFF image.

For the stable distribution (bullseye), this problem has been fixed in
version 1.4+really1.3.36+hg16481-2+deb11u1.

We recommend that you upgrade your graphicsmagick packages.
