DEBIAN-CVE-2026-84446

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.23.2, crafted HEIF sequence timing and edit-list data can make Track::initsampletimingtable compute a logical mnumoutputsamples value that exceeds the uint32t counters used by TrackVisual::decodenextimagesample and...

UBUNTU-CVE-2026-84447

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.1 and earlier, crafted grid, iovl, and iden reference graphs can repeatedly decode the same base image because processedids is copied per branch and ImageItem::decodeimage has no shared operation budget. This vulnerability is fix...

CVE-2026-84384 libheif: brotli/zlib decompression paths lack output-size limits, allowing decompression-bomb OOM/DoS

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.2, crafted HEIF or AVIF mime metadata and unci image data can cause decompressbrotli and doinflate to grow accumulated output without an effective size limit or MemoryHandle accounting. The brotli path has no outpu...

CVE-2026-62289

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker could exploit this vulnerability by providing a specially crafted HEIF or AVIF file containing a clean aperture box. This can lead to an integer underflow when processing image transformations, causing...
