Crash via JPEG dimension integer overflow
Published May 9, 2022 · Updated Aug 3, 2024
Integer overflow in HTMLDOC 1.9.16 allows local users to crash document conversion by processing a crafted JPEG image. The image_load_jpeg function multiplies unbounded image width, height, and depth values before malloc, allocating an undersized heap buffer that jpeg_read_scanlines writes past. Processing attacker-supplied HTML containing the image is required, and the demonstrated consequence is a process crash rather than data disclosure or modification.
