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...

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-2026-47254

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.0, Track::initsampletimingtable in libheif/sequences/track.cc stores an out-of-bounds chunk index mchunks.size into mpresentationtimeline when the number of chunks defined in the stco box is less than the number of...

Linux Distros Unpatched Vulnerability : CVE-2026-32740

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. Versions 1.21.2 and prior contain a heap- buffer-overflow write vulnerability in the grid tile...

EUVD-2026-30980

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, when decoding a HEIF grid image with strictdecoding=false the default, a corrupted tile silently fails to decode and the library returns heiferrorOk with no indication of failure, leading to an uninitialized...
