Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Summarysrc/libImaging/Jpeg2KDecode.c:853 accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile. That accumulated value is then used in the tilebytes calculation at src/libImaging/Jpeg2KDecode.c:868, which can make the decoder grow state-buffer vi...

CVE-2026-35591

libvips is a fast image processing library with low memory needs. The tiffload operation in libvips versions before and including 8.18.1 could incorrectly determine the number of channels in a JPEG or JPEG2000-encoded tile within a TIFF image, leading to a possible buffer overflow. This has been...

CVE-2026-35591

CVE-2026-35591 concerns libvips' TIFF decoding via the tiffload path. The issue arises when processing a TIFF image containing a JPEG/JPEG2000-encoded tile, where the number of channels could be mis-determined, enabling a possible heap-based buffer overflow. Affected versions are libvips ≤ 8.18.1...
