Comodo GeekBuddy, which is bundled with Comodo Anti-Virus, Comodo Firewall, and Comodo Internet Security, runs a passwordless, background VNC server and listens for incoming connections. This can allow for at least local privilege escalation on several platforms. It also may be remotely exploitable via CSRF-like attacks utilizing a modified web-based VNC client (eg. a Java VNC client).
