Title: BlackICE Agent not Firewalling After Standby BUG-ID: 2002019 Released: 06th Jun 2002 -------------------------------------------------------------------- Problem: ======== In a default installation, The BlackICE Agent might not reactivate when the host returns from standby. This could allow a malicious user to bypass the firewall completely. Vulnerable: =========== - BlackICE Agent 3.1 eal on Windows 2000 laptop Not Vulnerable: =============== - BlackICE Agent 3.1 ebh on Windows 2000 laptop Details: ======== The BlackICE Agent setup contains the parameter "restart.whenSuspend", which should be enabled by default. This, however, is not always the case, and as a result the firewall might not reactivate after a system standby. The BlackICE Agent would still give all the appearences of being active, but the filter function would not be in effect, and network communication would be possible to the same extent as if the software wasn't installed.
