EUVD-2026-47710

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.19.0 through 1.21.2 have a heap OOB read in ImageItemGrid::decodegridtile via irot-induced tile-coordinate underflow. Version 1.22.0 fixes the issue...

CVE-2026-47714

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. An integer overflow vulnerability exists in the inline mask parsing code, where the product of image width and height can exceed the maximum 32-bit unsigned integer value. This leads to an undersized buffer allocation,...

CVE-2026-47247 libheif Vulnerable to Heap Information Disclosure via Grid Image Gap + Uninitialized Pixel Plane Allocation

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.0, two bugs in libheif chain to leak process heap memory as visible pixel values in decoded grid images. An attacker who uploads a crafted AVIF/HEIC file to any server-side image processor WordPress, Sharp/libvips,...
