Description
In mprivacy-tools before 2.0.406g in m-privacy TightGate-Pro Server, a Directory Traversal in the print function of the VNC service allows authenticated attackers (with access to a VNC session) to automatically transfer malicious PDF documents by moving them into the .spool directory, and then sending a signal to the VNC service, which automatically transfers them to the connected VNC client's filesystem.
