Memory leak in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (memory exhaustion) via ICMP echo packets that trigger a bug in ip_output() in which the reference count for a routing table entry is not decremented, which prevents the entry from being removed.

Security readout for executives and security teams

CVE-2002-0574 is an old FreeBSD denial-of-service issue. FreeBSD 4.5 and earlier can leak memory when handling certain ICMP echo traffic, eventually exhausting memory and disrupting service. This mainly matters for legacy or embedded systems still running obsolete FreeBSD versions. Exposure is likely limited to internet-facing or network-reachable systems still running FreeBSD 4.5 or earlier. Modern supported FreeBSD versions are not identified as affected in the provided sources. Treat as a legacy-system risk. If no FreeBSD 4.5-or-earlier systems exist, business urgency is low. If such systems support critical services, prioritize remediation because a remote network event could disrupt availability. Mitigation focus: Inventory systems for FreeBSD 4.5 or earlier.; Prioritize replacement or upgrade of obsolete FreeBSD installations.; Review the FreeBSD-SA-02:21 advisory for vendor-specific remediation..
