A heap buffer overflow in image_set_mask function of HTMLDOC before 1.9.15 allows an attacker to write outside the buffer boundaries.
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.
The product writes data past the end, or before the beginning, of the intended buffer.
