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...

EUVD-2026-31501

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...
