Heap-based buffer overflow in the NeXT RLE decoder in the TIFF library (libtiff) before 3.8.2 might allow context-dependent attackers to execute arbitrary code via unknown vectors involving decoding large RLE images.
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.
