Struktur Libheif vulnerabilities

CVE-2025-68431 [HIGH] CWE-125 CVE-2025-68431: libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF that exercises the overlay image item path triggers a heap buffer over-read in `HeifPixelImage::overlay()`. The function computes a negative row length (likely from an unclipped overlay rectangle or invalid offsets), which then underflows when converte
