If that. This weekend I ran into a TIFF decoding issue (Canon scanner produces TIFFs with embedded JPEG compression with different parameters than the outer TIFF container). This is an issue with libtiff and affects any Mac or iOS app using CoreGraphics, anything using ImagMagick, etc. GIMP, Nikon NX Viewer, and others with their own TIFF implementations are unaffected.
I doubt anyone at Apple cares. If a CVE is filed for libtiff, they’ll rebase, but I doubt they are actively fuzzing it or even have regression tests for it.
