Unknown vulnerability in ip_nat_sack_adjust of Netfilter in Linux kernels 2.4.20, and some 2.5.x, when CONFIG_IP_NF_NAT_FTP or CONFIG_IP_NF_NAT_IRC is enabled, or the ip_nat_ftp or ip_nat_irc modules are loaded, allows remote attackers to cause a denial of service (crash) in systems using NAT, possibly due to an integer signedness error.

Security readout for executives and security teams

CVE-2003-0467 affects old Linux NAT systems using specific Netfilter FTP or IRC NAT helpers. A remote attacker could crash the system, causing denial of service. The available record does not provide CVSS scoring, confirmed exploitation, or detailed vendor fix information. Exposure is mainly legacy Linux NAT gateways or firewalls running kernel 2.4.20 or some 2.5.x builds with FTP or IRC NAT helper support enabled or loaded. Treat this as a legacy infrastructure risk. Prioritize if old Linux NAT gateways still protect business networks, because a remote crash can interrupt connectivity. Mitigation focus: Inventory legacy Linux NAT gateways and firewall appliances.; Check whether FTP or IRC NAT helper modules are enabled or loaded.; Consult vendor or distribution guidance for fixed kernel packages..
