CVE-2022-35003Public exploit

Memory corruption via out-of-bounds grayscale pixel write

Published Aug 16, 2022 · Updated Aug 3, 2024

Global buffer overflow in JPEGDEC commit be4843c allows context-dependent attackers to corrupt memory via a crafted JPEG image. JPEGPutMCU8BitGray writes a decoded grayscale byte 1,120 bytes past the 16,384-byte ucDitherBuffer in src/jpeg.inl. An application must decode the malicious file; the published reproducer triggers an AddressSanitizer abort, while code execution is not demonstrated.
