ipfw in FreeBSD 5.4, when running on Symmetric Multi-Processor (SMP) or Uni Processor (UP) systems with the PREEMPTION kernel option enabled, does not sufficiently lock certain resources while performing table lookups, which can cause the cache results to be corrupted during multiple concurrent lookups, allowing remote attackers to bypass intended access restrictions.

Security readout for executives and security teams

CVE-2005-2019 affects FreeBSD 5.4 systems using ipfw with the PREEMPTION kernel option. A locking flaw during firewall table lookups can corrupt cached results under concurrent lookups, potentially letting remote traffic bypass intended access restrictions. Exposure appears limited to FreeBSD 5.4 systems running ipfw with PREEMPTION enabled. The provided sources do not identify other affected versions, products, or configurations. Prioritize if legacy FreeBSD 5.4 firewalls or hosts still enforce network access controls with ipfw. For modern environments without FreeBSD 5.4, business urgency is likely low. Mitigation focus: Identify any FreeBSD 5.4 systems using ipfw and PREEMPTION.; Review FreeBSD-SA-05:13 for official remediation guidance.; Apply vendor-supported patches or configuration changes from the advisory..
