Sun Ray Server Software 4.0 and 4.1 does not generate a unique DSA private key for the firmware on each Sun Ray 1, 1g, 100, and 150 DTU device, which makes it easier for remote attackers to obtain sensitive information by predicting a key and then using it to decrypt sniffed network traffic.

Sun Ray Server Software 4.1 on Solaris 10, when Automatic Multi-Group Hotdesking (AMGH) is enabled, responds to a logout action by immediately logging the user in again, which makes it easier for physically proximate attackers to obtain access to a session by going to an unattended DTU device.

Unspecified vulnerability in the Authentication Manager (aka utauthd) in Sun Ray Server Software 4.0 and 4.1 allows remote attackers to execute arbitrary code or cause a denial of service via unknown vectors.
