Description

Novacoast has reported a vulnerability in Novell Netware, which can be exploited by a malicious person with physical access to a system to bypass the password protected screensaver.

The problem is that some hotkeys are still enabled when the password protected "nlm" screensaver locks a console. This can be exploited to shutdown the screensaver via e.g. the Netware debugger triggered by the ALT-SHIFT-SHIFT-ESC key combination.

The vulnerability has been reported in versions 5.1, 6.0, and 6.5.


Solution
Apply Novell BorderManager ICSA Compliance Kit version 5.0d (see original advisory).
