CVE-2004-1323: Multiple syscalls in the compat subsystem for NetBSD before 2.0 allow local users to cause a denial of serv...

Security readout for executives and security teams

This is a historical NetBSD kernel issue affecting versions before 2.0. A local user could send malformed signal-related syscall input through the compatibility subsystem and crash the system. The main business impact is service disruption on legacy NetBSD hosts, especially shared or multi-user systems. Exposure is likely limited to legacy systems running NetBSD before 2.0, particularly where untrusted local shell or application users exist. Modern NetBSD deployments are unlikely to be affected if upgraded beyond the pre-2.0 line. Low to moderate for most organizations because this affects very old NetBSD systems and requires local access. Treat as higher priority if legacy NetBSD hosts support shared users, production services, or critical embedded workloads. Mitigation focus: Identify any NetBSD hosts running versions before 2.0.; Upgrade affected systems to NetBSD 2.0 or later where feasible.; Review NetBSD-SA2004-010 for vendor-specific remediation details..
