It has been discovered that Metaframe can be made to become unstable. By connecting to the Metaframe server using custom-crafted Java ICA files, a remote user may be able to create instability in the Metaframe server. The server typically reacts to this vulnerability by disconnecting all users, and either crashing requiring a manual reboot, or crashing and rebooting.
