The (1) Windows and (2) Java client programs for the ATEN KH1516i IP KVM switch with firmware 1.0.063 and the KN9116 IP KVM switch with firmware 1.1.104 do not properly use RSA cryptography for a symmetric session-key negotiation, which makes it easier for remote attackers to (a) decrypt network traffic, or (b) conduct man-in-the-middle attacks, by repeating unspecified "client-side calculations."

The Java client program for the ATEN KH1516i IP KVM switch with firmware 1.0.063 and the KN9116 IP KVM switch with firmware 1.1.104 has a hardcoded AES encryption key, which makes it easier for man-in-the-middle attackers to (1) execute arbitrary Java code, or (2) gain access to machines connected to the switch, by hijacking a session.

The ATEN KH1516i IP KVM switch with firmware 1.0.063 and the KN9116 IP KVM switch with firmware 1.1.104 do not (1) encrypt mouse events, which makes it easier for man-in-the-middle attackers to perform mouse operations on machines connected to the switch by injecting network traffic; and do not (2) set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

The https web interfaces on the ATEN KH1516i IP KVM switch with firmware 1.0.063, the KN9116 IP KVM switch with firmware 1.1.104, and the PN9108 power-control unit have a hardcoded SSL private key, which makes it easier for remote attackers to decrypt https sessions by extracting this key from their own switch and then sniffing network traffic to a switch owned by a different customer.

The protocol_client_msg function in vnc.c in the VNC server in (1) Qemu 0.9.1 and earlier and (2) KVM kvm-79 and earlier allows remote attackers to cause a denial of service (infinite loop) via a certain message.
