CVE-2026-84451: Out-of-bounds Read

libheif is a HEIF and AVIF file format decoder and encoder. From 1.19.0 until 1.23.3, the no-icef full-item branch of uncdecoder::getcompressedimagedatauncompressed in libheif/codecs/uncompressed/uncdecoder.cc retains an addition-based range check that can wrap when a crafted uncompressed tile gr...

JLSEC-2026-1095

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 o...
