UBUNTU-CVE-2026-84446

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.23.2, crafted HEIF sequence timing and edit-list data can make Track::initsampletimingtable compute a logical mnumoutputsamples value that exceeds the uint32t counters used by TrackVisual::decodenextimagesample and...
