Application crash via unchecked JPEG coefficient arithmetic
Published Apr 15, 2022 · Updated Aug 3, 2024
Integer overflow in stb_image.h 2.27 allows context-dependent attackers to crash applications by supplying a crafted progressive JPEG image. During progressive JPEG DC decoding, stbi__jpeg_decode_block_prog_dc multiplies and accumulates attacker-derived coefficients in signed integers without overflow checks. An application must decode the crafted file; the demonstrated consequence is a process crash, with no reported data disclosure or modification.
