libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.1, a crafted uncompressed HEIF image using generic zlib unci full-item compression can crash an application that decodes an advertised tile with heifimagehandledecodeimagetile. In...

EUVD-2026-62188

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted HEIF or AVIF file containing a clean aperture box can reduce an image dimension to zero and crash or corrupt tiling results when heifimagehandlegetimagetilinghandle, 1, &tiling is called...

CVE-2026-50142

libheif 1.19.0–1.23.0 is vulnerable to denial-of-service via crafted HEIF sequences: Box_stsz::parse() omits bound checks in fixed-size mode, and Track::load() 32-bit arithmetic wraparound bypasses consistency checks, allowing multi-gigabyte allocations. No in-the-wild exploitation reported. Fixe...

CVE-2026-50142 libheif: unbounded heap allocation in HEIF sequence parser (stsz fixed-size mode missing bound check)

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.0, a crafted HEIF sequence accepted by heifcontextreadfrommemory with the msf1 sequence brand can cause unbounded heap allocation. In libheif/sequences/seqboxes.cc, Boxstsz::parse applies maxsequenceframes only to...

CVE-2026-47178

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A local attacker could exploit this vulnerability by convincing a user to open a specially crafted HEIF file. This crafted file triggers a heap out-of-bounds write, which can lead to arbitrary code execution. This could...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the decodegridtile process. An attacker can cause a heap out-of-bounds read by supplying a crafted image file that triggers an irot-induced tile-coordinate underflow. Remediation Upgrade libheif to version 1.23.1 o...

EUVD-2026-47710

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.19.0 through 1.21.2 have a heap OOB read in ImageItemGrid::decodegridtile via irot-induced tile-coordinate underflow. Version 1.22.0 fixes the issue...

CVE-2026-48029

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.19.0 through 1.21.2 have a heap OOB read in ImageItemGrid::decodegridtile via irot-induced tile-coordinate underflow. Version 1.22.0 fixes the issue...

CVE-2026-47714

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. An integer overflow vulnerability exists in the inline mask parsing code, where the product of image width and height can exceed the maximum 32-bit unsigned integer value. This leads to an undersized buffer allocation,...

CVE-2026-47709

A flaw was found in libheif, a library for decoding and encoding HEIF High Efficiency Image File Format and AVIF AV1 Image File Format images. A local attacker could provide a specially crafted HEIF image file that, when processed, causes the application to crash due to a null pointer read. This...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the libheif/region.cc process. An attacker can trigger out-of-bounds memory access by crafting a HEIF file with large width and height values that cause an integer overflow during buffer allocation...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the vvdecpushdata2 function. An attacker can cause an out-of-bounds heap read by supplying a crafted HEIF file with a VVC track that exploits an integer overflow in the security check, bypassing intended...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write via the unci tile decoding process.
