Amazon Linux 2023 : heif-pixbuf-loader, libheif, libheif-devel (ALAS2023-2026-1814)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1814 advisory. 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...

CVE-2026-41069: Out-of-bounds Read

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, a malformed HEIF sequence file can trigger an out-of-bounds read in core sequence parsing logic, causing DoS. A malformed file can have stco.entrycount == 0 creating no chunks while still passing validation...

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...

Use of Uninitialized Resource

Overview Affected versions of this package are vulnerable to Use of Uninitialized Resource in the decoding process of grid-based HEIF or AVIF images when a corrupted tile fails to decode and the library returns a success status, resulting in uninitialized heap memory being exposed as pixel data. ...

UBUNTU-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-2026-32814

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, when decoding a HEIF grid image with strictdecoding=false the default, a corrupted tile silently fails to decode and the library returns heiferrorOk with no indication of failure, leading to an uninitialized...

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-2026-32741: Heap-based Buffer Overflow

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and below contain a heap buffer overflow in MaskImageCodec::decodemaskimage. When decoding a HEIF file containing a mask image mski, the function copies the full iloc extent data into a pixel buffer using memcpydst,...

CVE-2026-32740: Out-of-bounds Write

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...

libheif buffer error vulnerability

Libheif is a open-source decoder and encoder for the ISO/IEC 23008-12:2017 HEIF file format developed by Struktur. Versions of Libheif prior to 1.21.2 contain a buffer error vulnerability. This vulnerability stems from a heap buffer overflow during tile composition, allowing attackers to write...

CVE-2026-32814: Exposure of Sensitive Information to an Unauthorized Actor

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, when decoding a HEIF grid image with strictdecoding=false the default, a corrupted tile silently fails to decode and the library returns heiferrorOk with no indication of failure, leading to an uninitialized...

PT-2026-36267

libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF that exercises the overlay image item path triggers a heap buffer over-read in HeifPixelImage::overlay. The function computes a negative row length likely from an unclipped overlay rectangle or...
