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.
