CVE-2023-53156Public exploit

Buffer overwrite via overflowing dimension-product check

Published Jul 27, 2025 · Updated Jul 28, 2025

Buffer overflow in Elliott Mahler Transpose 0.1.0 through 0.2.2 allows attackers to write beyond an output slice via crafted dimensions. The transpose::transpose safety check multiplies input_width by input_height without overflow detection, so a wrapped product can equal both slice lengths before unsafe writes proceed. Exploitation requires a release build and dimension values whose wrapped product matches the input and output lengths; successful triggering corrupts memory or crashes the consuming process.
