Description d'origine
La description telle que publiée par la source (souvent en anglais).
libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.19.0 through 1.21.2, a crafted HEIF file (uncompressed unci codec, tiled, component-interleaved, 4:2:0) triggers a heap out-of-bounds write in libheif's uncompressed tile decoder. The write overwrites the C++ vtable pointer of an adjacent unc_decoder_component_interleave object; the next virtual call dispatches to an attacker-chosen address. Version 1.22.0 patches the issue.
