Notes

[jessie] - imagemagick <not-affected> (vulnerable code not present)
https://github.com/ImageMagick/ImageMagick/issues/1225
Only in the 7.x series the assert statement was changed so the statement would
be true even if image is NULL, but image_info is not:
https://github.com/ImageMagick/ImageMagick/commit/db2a1d6aaff3a83a74b37731405424c95f0c873a
Fixed by: https://github.com/ImageMagick/ImageMagick/commit/2c75f301d9ac84f91071393b02d8c88c8341c91c
check if though missing null checks are present as well in 6.x series
