Technical details
A use-after-scope vulnerability exists in the TIFF input handler's multithreaded scanline decompression path. When TIFFInput::read_native_scanlines() exits early on certain error conditions, background worker tasks attempt to access stack variables (ok and compressed_scratch) after they have been destroyed, resulting in a denial of service crash. The vulnerability requires TIFF multithreading to be enabled and a specially crafted compressed TIFF file as input.
