OptixPro [Symantec-2004-020615-3137-99] (Backdoor.OptixPro.13.C) - trojan horse that opens a backdoor on TCP port 4001.

The Festo CECX-X-C1 Modular Master Controller with CoDeSys and CECX-X-M1 Modular Controller with CoDeSys and SoftMotion do not require authentication for connections to certain TCP ports, which allows remote attackers to (1) modify the configuration via a request to the debug service on port 4000 or (2) delete log entries via a request to the log service on port 4001.

A denial-of-service vulnerability exists in the Pixar Renderman IT Display Service 21.6 (0x67). The vulnerability is present in the parsing of a network packet without proper validation of the packet. The data read by the application is not validated, and its use can lead to a null pointer dereference. The IT application is opened by a user and then listens for a connection on port 4001. An attacker can deliver an attack once the application has been opened.
