CVE-2026-62292

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...

Updated libheif packages fix security vulnerabilities

libheif has a Heap OOB Read/SEGV Crash via Zero samplesperchunk. CVE-2026-32738 libheif is Vulnerable to Infinite Loop DoS via stts Sample Duration Lookup. CVE-2026-32739 Heap-Buffer-Overflow Write in Grid Tile Chroma Compositing. CVE-2026-32740 libheif has a heap buffer overflow in...

Important: libheif

Issue Overview: A critical heap-based buffer overflow vulnerability exists in libheif v1.21.2 and likely earlier versions within the handling of uncompressed HEIF images ISO/IEC 23001-17, unci item type. When processing a tiled image with chroma subsampling e.g., 4:2:0 or 4:2:2, the library fails...

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 Upgrade libheif to...

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...
