Apple LinkPresentation HEIC Out-Of-Bounds Write

Apple LinkPresentation contains an out-of-bounds write when processing a maliciously crafted image. The proof of concept generates mismatched HEIC frames and fetches the image through Open Graph link metadata. https://packetstorm.news/download/238556...

K000163661: libheif vulnerability GHSA-g89c-p67h-r497

Security Advisory Description A crafted HEIC/HEIF/AVIF file with nested identity-derivation iden and auxiliary auxl item references causes HeifPixelImage::scalenearestneighbor to write 16-bit samples into an 8-bit Alpha plane allocation, producing a heap buffer overflow OOB write. The overflow si...

Wordfence Argus Discovers Critical Vulnerability in libheif, the Library That Opens iPhone Photos on Your Server

On September 1, 2026, the libheif project released version 1.23.3, closing a critical heap buffer overflow that the Wordfence Threat Intelligence team, using Wordfence Argus, discovered and reported four days earlier. The libheif maintainer, Dirk Farin, gave it a score of 9.8 out of 10 on the CVS...

CVE-2026-84383

libheif is a HEIF and AVIF file format decoder and encoder. From 1.22.0 until 1.23.2, a crafted HEIF, HEIC, or AVIF item graph using nested iden and auxl references can make HeifPixelImage::transferchannelfromimageas append duplicate Alpha planes with different bit depths to mstorage...

Infinite loop

Overview exifreader is a Library that parses Exif metadata in images. Affected versions of this package are vulnerable to Infinite loop via a malformed ISO-BMFF iloc box in HEIC/AVIF files, parsed by parseItemLocationBox in src/image-header-iso-bmff-iloc.js. When the declared extentCount field in...

CVE-2026-85715

ExifReader is a JavaScript Exif information parser. Prior to 4.41.1, ExifReader parses attacker-controlled HEIC or AVIF ISO-BMFF files in getItems within src/image-header-iso-bmff-iloc.js and trusts iloc itemCount and extentCount values while allocating an extent object for every nested-loop...
