An update that contains security fixes can now be installed.

Description:



GraphicsMagick was updated to 1.3.29:

* Security Fixes:

- GraphicsMagick is now participating in Google's oss-fuzz project
- JNG: Require that the embedded JPEG image have the same dimensions as
the JNG image as provided by JHDR. Avoids a heap write overflow.
- MNG: Arbitrarily limit the number of loops which may be requested by
the MNG LOOP chunk to 512 loops, and provide the '-define
mng:maximum-loops=value' option in case the user wants to change the
limit. This fixes a denial of service caused by large LOOP
specifications.

* Bug fixes:

- DICOM: Pre/post rescale functions are temporarily disabled (until the
implementation is fixed).
- JPEG: Fix regression in last release in which reading some JPEG files
produces the error "Improper call to JPEG library in state 201".
- ICON: Some DIB-based Windows ICON files were reported as corrupt to an
unexpectedly missing opacity mask image.
- In-memory Blob I/O: Don't implicitly increase the allocation size
due
to seek offsets.
- MNG: Detect and handle failure to allocate global PLTE. Fix divide by
zero.
- DrawGetStrokeDashArray(): Check for failure to allocate memory.
- BlobToImage(): Now produces useful exception reports to cover the
cases where 'magick' was not set and the file format could not
be
deduced from its header.

* API Updates:

- Wand API: Added MagickIsPaletteImage(), MagickIsOpaqueImage(),
MagickIsMonochromeImage(), MagickIsGrayImage(), MagickHasColormap()
based on contributions by Troy Patteson.
- New structure ImageExtra added and Image 'clip_mask' member is
replaced by 'extra' which points to private ImageExtra
allocation. The
ImageGetClipMask() function now provides access to the clip mask image.
- New structure DrawInfoExtra and DrawInfo 'clip_path' is replaced
by
'extra' which points to private DrawInfoExtra allocation. The
DrawInfoGetClipPath() function now provides access to the clip path.
- New core library functions: GetImageCompositeMask(),
CompositeMaskImage(), CompositePathImage(), SetImageCompositeMask(),
ImageGetClipMask(), ImageGetCompositeMask(), DrawInfoGetClipPath(),
DrawInfoGetCompositePath()
- Deprecated core library functions: RegisterStaticModules(),
UnregisterStaticModules().

* Feature improvements:
- Static modules (in static library or shared library without
dynamically loadable modules) are now lazy-loaded using the same
external interface as the lazy-loader for dynamic modules. This
results in more similarity between the builds and reduces the fixed
initialization overhead by only initializing the modules which are
used.
- SVG: The quality of SVG support has been significantly improved due to
the efforts of Greg Wolfe.
- FreeType/TTF rendering: Rendering fixes for opacity.
