CyberRota Analysis
AI-GeneratedThe libheif library, used for HEIF and AVIF file format encoding and decoding, is vulnerable to an integer overflow in the color conversion process for extremely large RGB images, which can lead to invalid memory access and potentially crash the encoding process. Users and developers relying on versions prior to 1.19.6 should prioritize updating to mitigate this risk, especially those handling large image files. While the severity is classified as low, the potential for application instability warrants attention.

Original NVD Description
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.
