NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference in the heifimagehandlegetimagetiling function when processing a malformed uncompressed HEIF image item that has an associated uncC property but lacks an associated ispe property. An attacker can cause a crash by...

EUVD-2026-46451

libheif is a HEIF and AVIF file format decoder and encoder. Versions prior to 1.22.0 crashes in the public C API heifimagehandlegetimagetiling when a malformed uncompressed HEIF image item has an associated uncC property but no associated ispe property. In debug builds this trips the ispe && uncC...

CVE-2026-47709

libheif (HEIF/AVIF decoder/encoder) has a null pointer dereference in heif_image_handle_get_image_tiling for malformed uncompressed image items with uncC but no ispe. In debug builds this triggers an ispe && uncC assertion; in release/ASan builds it can cause a null read at address 0xa8. Affected...

CVE-2026-54058

Pillow is a Python imaging library. Prior to 12.3.0, when Pillow loads an uncompressed McIdas AREA image from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width, causing pixel access such as Image.tobytes, getpixel,...
