Application crash via wrapped raw2tiff buffer allocation
Published Oct 5, 2023 · Updated Jan 22, 2026
Integer overflow in LibTIFF raw2tiff before 4.6.0 allows remote attackers to crash the utility through crafted dimensions and raw image input. Negative width and band values become large unsigned integers, bypass guess_size, wrap linebytes and bufsize to undersized values, and drive memcpy past the heap buffer. Exploitation requires a user or application to run raw2tiff with attacker-influenced options and input; the published evidence establishes a crash, while code execution remains unverified.
