Multiple stack-based buffer overflows in unrtf 0.21.9 allow remote attackers to cause a denial-of-service by writing a negative integer to the (1) cmd_expand function, (2) cmd_emboss function, or (3) cmd_engrave function.
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.
