Xianrui Dong discovered that libheif had an out-of-bounds read in its HEIF sequence track parser. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. This issue only affected Ubuntu 26.04 LTS. CVE-2026-47254 Junyi Liu discovered that libheif had...

Linux Distros Unpatched Vulnerability : CVE-2026-50142

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The vulnerability exists due to a missing boundary check on the sample size stsz box fixed-size parameter inside the HEIF sequence parser of libheif. When a...

CVE-2026-49271

A flaw was found in libheif, a decoder and encoder for HEIF and AVIF file formats. A remote attacker could exploit this vulnerability by providing a specially crafted HEIF file. The uncompressed HEIF decoder's validation of icef compressed-unit offsets can experience an integer wrap-around. This...

USN-8479-1: libheif vulnerabilities

It was discovered that libheif incorrectly handled certain crafted HEIF files. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. CVE-2026-47178 It was discovered that libheif incorrectly validated offsets when decoding certain crafted HEIF files. An...

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 800-byte HEIF sequence file could cause an infinite loop in the Boxstts::getsampleduration function. This loop consumed 100% of the CPU resources indefinitely, with no progress being made,...

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...

Linux Distros Unpatched Vulnerability : CVE-2025-71319

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

Linux Distros Unpatched Vulnerability : CVE-2026-49271

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offse...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the uncompressed HEIF decoder process. An attacker can cause a crash by supplying a crafted HEIF file that manipulates compressed-unit offsets to trigger an out-of-bounds heap read. Remediation A fix was pushed int...

CVE-2026-49271

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unitoffset + unitsize. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector...

CVE-2026-49271 libheif: Wrapped icef compressed-unit range check causes out-of-bounds read in uncompressed HEIF decoder

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unitoffset + unitsize. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector...

CVE-2025-62821

Microsoft HEIF Image Extensions 1.2.22.0 has an out-of-bounds read because CHEIFItemInfoEntryGetDataSize can return success while leaving the reported data size as 0. This causes a caller to make a 1-byte allocation. Later, CopyPixels computes copysize = stride absroiheight but does not check the...
