Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the SampleAuxInfoReader constructor when parsing a specially crafted HEIF sequence file containing a saiz box that declares more samples than exist in the track's chunk table. An attacker can cause a heap buffer over-read by supplying a malicious file, potentially leading to information disclosure or application crash during file parsing.
