IRC DCC helper in the ip_masq_irc IP masquerading module 2.2 allows remote attackers to bypass intended firewall restrictions by causing the target system to send a "DCC SEND" request to a malicious server which listens on port 6667, which may cause the module to believe that the traffic is a valid request and allow the connection to the port specified in the DCC SEND request.

Security readout for executives and security teams

This older Linux IP masquerading issue could let a remote party trick an IRC helper into opening firewall paths that administrators did not intend. The provided record does not include CVSS, named affected distributions, or current exploitation evidence. Exposure is most likely limited to legacy Linux 2.2-era systems using IP masquerading with the ip_masq_irc helper and IRC/DCC traffic. The bundle does not identify modern affected products or distributions. Treat this as a legacy-infrastructure risk rather than a broad modern emergency. Prioritize discovery of old Linux firewall/NAT systems and replacement planning if any are still in production. Mitigation focus: Inventory any Linux 2.2-era masquerading firewalls or embedded systems.; Check vendor or distribution guidance for fixed kernel or module packages.; Retire or isolate legacy NAT/firewall hosts that still require this helper..
