In multispectral MIFF image processing in ImageMagick before 7.1.1-44, packet_size is mishandled (related to the rendering of all channels in an arbitrary order).
ImageMagick is a free and open-source software suite, used for editing and manipulating digital images. The `AppImage` version `ImageMagick` might use an empty path when setting `MAGICK_CONFIGURE_PATH` and `LD_LIBRARY_PATH` environment variables while executing, which might lead to arbitrary code execution by loading malicious configuration files or shared libraries in the current working directory while executing `ImageMagick`. The vulnerability is fixed in 7.11-36.
