This advisory pertains to an indeterminant class of networked embedded controllers and processors.
Vulnerable controllers are prone to hang or shutdown shortly after receiving the attacking packets.
The failure can extend even to their non-network functionality and can cause the controlled equipment to fail. There exists a significant possibility of the controlled equipment being left in a non-safe or inoperable condition, possibly leading to physical damage. Unfortunately, executing the attack also creates the potential of causing a failure in the controller. Some versions of the OS-9 operating system are known to be affected by this vulnerability. It has not been determined whether or not all versions of OS-9 are affected.
