CVE-2026-84450

A flaw was found in libheif. A remote attacker could provide a specially crafted image file that, when processed by the libheif library, can lead to an integer overflow during crop calculations. This issue can cause assert-enabled builds to abort, resulting in a denial of service DoS. In release...

CVE-2026-84447

A flaw was found in libheif, a software library for decoding and encoding HEIF and AVIF image files. A remote attacker could exploit this by providing a specially crafted image file. This crafted file could cause the library to repeatedly process the same image data, leading to excessive use of t...

CVE-2026-84446

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker could provide a crafted HEIF file containing malicious sequence timing and edit-list data. This could lead to non-terminating decode loops and unbounded memory allocation, resulting in severe CPU and...

CVE-2026-84384

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 crafted HEIF or AVIF file containing malicious metadata or image data. This could cause the application to consume an unbounded amount of memory during...

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-2026-84444

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.23.2, when WITHUNCOMPRESSEDCODEC is enabled, heifcontextaddimagetile accepts an independently constructed tile whose component-plane dimensions do not match the tile geometry established by the prototype image...

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...
