Linux Distros Unpatched Vulnerability : CVE-2026-32740

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap- buffer-overflow write vulnerability in the grid tile...

SUSE CVE-2026-32740

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap-buffer-overflow write vulnerability in the grid tile compositing, allowing an attacker to write 64 bytes of fully attacker-controlled data past the end of a chroma plane heap allocation by craftin...

CVE-2026-32740

A flaw was found in libheif, a library for decoding and encoding HEIF and AVIF image files. This heap-buffer-overflow vulnerability allows a remote attacker to write arbitrary data beyond the intended memory boundary. By crafting a malicious HEIF/AVIF file with a specific grid tile configuration,...

CVE-2026-32814

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. When processing a specially crafted HEIF or AVIF image containing a corrupted grid tile, the library fails to properly initialize memory. This can lead to an information disclosure, where uninitialized heap memory,...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write through the image decoding process when handling grid tile chroma compositing. An attacker can execute arbitrary code or cause a denial of service by crafting a specially designed HEIF/AVIF file with a 1×4 grid of...
