How to fix?

Upgrade Debian:10 libheif to version 1.3.2-2~deb10u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libheif package and not the libheif package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

libheif 1.4.0 has a use-after-free in heif::HeifContext::Image::set_alpha_channel in heif_context.h because heif_context.cc mishandles references to non-existing alpha images.
