CVE-2025-71319

image-size through 2.0.2 contains a denial of service vulnerability that allows remote attackers to permanently block the Node.js event loop by supplying a specially crafted image buffer with a zero-valued size field in a recognized box-type. Attackers can trigger an infinite loop in the JXL or...

CVE-2025-71319

CVE-2025-71319 affects image-size versions 1.1.0 before 1.2.1 and 2.0.0 before 2.0.2. The vulnerability resides in the findBox function, triggered when processing crafted images with zero-sized boxes (JXL, HEIF, or JP2), causing an infinite loop and denial of service. The issue could lead to appl...

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

A flaw was found in libheif, a HEIF High Efficiency Image File Format and AVIF file format decoder and encoder. A remote attacker could exploit this vulnerability by providing a specially crafted, malformed HEIF sequence file. This malformed file can trigger an out-of-bounds read during the core...

JLSEC-2026-574

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, a crafted HEIF sequence file where the saiz box declares more samples than actually exist in the track's chunk table causes a heap-buffer-overflow out-of-bounds read in the SampleAuxInfoReader constructor. T...

JLSEC-2026-571

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 800-byte HEIF sequence file causes an infinite loop in Boxstts::getsampleduration, consuming 100% CPU indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and...

JLSEC-2026-570

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 792-byte HEIF sequence file with samplesperchunk=0 in the stsc box causes an unsigned integer underflow in the Chunk constructor mlastsample = 0 + 0 - 1 = UINT32MAX, mapping all samples to an empty...
