Stack-based buffer overflow in Ubisoft Rayman Legends before 1.3.140380 allows remote attackers to execute arbitrary code via a long string in the "second connection" to TCP port 1001.
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.
