There is an illegal WRITE memory access at common-image.c (function load_image) in libcaca 0.99.beta19 for 1bpp data.
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.
