NVD Description

Note: Versions mentioned in the description apply only to the upstream gdk-pixbuf-loader-libheif package and not the gdk-pixbuf-loader-libheif package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unit_offset + unit_size. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector from iterators outside the compressed item buffer, producing an out-of-bounds heap read and crash. Version 1.22.1 patches the issue.
