Mikrotik RouterOs prior to stable 6.47 suffers from a memory corruption vulnerability in the /nova/bin/bfd process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference).
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.
