Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the core sequence parsing process. An attacker can cause a crash or denial of service by providing a specially crafted HEIF file that manipulates the stco.entry_count, saio.entry_count, and saiz.sample_count values to trigger an out-of-bounds dereference.
