CVE-2026-84449: Integer Overflow or Wraparound

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.19.6, OpRGB2432toYCbCr::convertcolorspace stores image-plane strides in an integer width that can overflow for extremely large RGB images created through heifimagecreate and heifimageaddplane. The resulting wrapped stride caus...

CVE-2026-52492

A flaw was found in libtiff. An integer overflow vulnerability exists in the cvtRaster function of the rgb2ycbcr utility. When processing a specially crafted TIFF image during YCbCr conversion, an attacker could trigger an undersized heap allocation, leading to a heap-based buffer overflow. This...
