The Acronis Agent is "an essential component of Acronis True Image Echo Server (Workstation and Enterprise packages) and is a server running on the TCP and UDP port 9876 which allows the local and remote management of Acronis TrueImage". A vulnerability in the way the Acronis True Image Windows Agent handles incoming traffic allows remote attackers to cause the service to crash.
