LibTIFF version 4.0.7 is vulnerable to a heap buffer overflow in the tools/tiffcp resulting in DoS or code execution via a crafted BitsPerSample value.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
