graphicsmagick (1.4+really1.3.36-1) unstable; urgency=high

  * New upstream release, fixing the following security issues:
    - update almost all of the remaining coders to use the resource-limited
      memory allocator,
    - ReadMPCImage(): heap-buffer-overflow read,
    - EdgeImage(): fix null pointer dereference if edge image failed to be
      created,
    - CompareImageCommand() and CompositeImageCommand(): fix memory leaks when
      an input image failed to be read,
    - fix several null pointer dereference if an image failed to be created,
    - Classify(): remove variables from function global scope that don't need
      outer scope,
    - ReadMIFFImage() and ReadMPCImage(): arbitrarily limit the number of
      header keywords to avoid DOS attempts.
