libheif: libheif is a HEIF and AVIF file format decoder and encoder
CVE-2026-84449 is fixed in 17 products on 1 platform, first by DEBIAN-CVE-2026-84449, released September 19, 2026. It is not reported as exploited. Patch Radar priority: Routine.
libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.19.6, Op_RGB24_32_to_YCbCr::convert_colorspace() stores image-plane strides in an integer width that can overflow for extremely large RGB images created through heif_image_create() and heif_image_add_plane(). The resulting wrapped stride causes the conversion loop in libheif/color-conversion/rgb2yuv.cc to compute an invalid input pointer and read beyond the allocated interleaved plane while heif_context_encode_image() performs RGB-to-YCbCr conversion. This can crash the encoding process. This issue is fixed in version 1.19.6.
