FontForge 20161012 is vulnerable to a heap-based buffer overflow in readcffset (parsettf.c) resulting in DoS or code execution via a crafted otf file.
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.
