ImageMagick encounter a read beyond an allocated heap buffer when reading CMYKA TIFF files which claim to offer fewer samples per pixel than required. A maliciously crafted file could cause the application to crash. Please see bug 611356 for details.
Still unknown status.
(In reply to Thomas Deutschmann from comment #1) > Still unknown status. Upstream commented on the Github page that they are not able to reproduce this based off the issue you opened. They closed it out 20 days ago.
Not reproducible by upstream or myself.
