CVE-2026-62377

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker could provide a specially crafted HEIF sequence. Processing this malicious file could lead to a reachable assertion or dereference an empty map, resulting in a crash of the application. This...

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...

CVE-2026-50142

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker can provide a specially crafted HEIF sequence that triggers an unbounded heap allocation. This occurs because the HEIF sequence parser's fixed-size mode is missing a bound check, and an integer...

Astra Linux – Vulnerability in libheif

libheif is a decoder and encoder for HEIF and AVIF file formats. Prior to version 1.21.0, a crafted HEIF file that used overlay image item paths triggered a heap buffer overflow in HeifPixelImage::overlay. This function calculated a negative row length likely derived from an unclipped overlay...

Astra Linux – Vulnerability in libheif

libheif is a decoder and encoder for HEIF and AVIF file formats. In versions 1.21.2 and earlier, a crafted HEIF sequence file where the saiz box declares more samples than actually exist in the track’s chunk table could cause a heap-buffer-overflow out-of-bounds read in the SampleAuxInfoReader...

The vulnerability of the HEIF and AVIF file encoding/decoding library lies in its ability to trigger service interruptions when reading data beyond the permissible buffer size.

The vulnerability of the HEIF and AVIF file encoding/decoding library lies in reading data from buffers beyond their acceptable limits. Exploiting this vulnerability could allow a malicious actor to cause service interruptions...

The vulnerability of the Box_stts::get_sample_duration() function in the HEIF and AVIF file encoding/decoding library allows a perpetrator to trigger a service failure.

The vulnerability of the Boxstts::getsampleduration function in the HEIF and AVIF file encoding/decoding library lies in the execution of a loop with an unreachable exit condition. Exploiting this vulnerability could allow a malicious actor to cause service failures...
