CVE-2000-0792: Gnome Lokkit firewall package before 0.41 does not properly restrict access to some ports, even if a user d...

Security readout for executives and security teams

An older Linux firewall tool called Gnome Lokkit (versions before 0.41) did not fully close off network ports as users expected. Even when a user chose not to expose any services, some ports remained reachable from the network, giving outsiders more access than intended. This is a legacy issue from 2000 that only matters if very old Linux systems are still in production. Exposure today is minimal. Gnome Lokkit was a late-1990s to early-2000s Red Hat Linux utility, superseded long ago by iptables/nftables front-ends and firewalld. Any modern Glexia or client environment is extremely unlikely to run affected versions. Residual risk exists only on unmaintained legacy hosts still running vintage Red Hat or GNOME 1.x distributions. Very low priority. This is a 25-year-old firewall misconfiguration in a long-obsolete Linux tool. No action is warranted unless asset inventory reveals ancient Red Hat systems still in operation, in which case the correct remedy is decommissioning or OS modernization rather than a targeted patch. Mitigation focus: Upgrade Gnome Lokkit to 0.41 or later, or migrate to a supported firewall like firewalld or nftables.; Retire any end-of-life Red Hat Linux hosts still using Lokkit as their firewall.; Enforce default-deny at a network firewall or security group in front of legacy hosts..
