IBM SecureWay Firewall before 4.2.2 performs extra processing before determining that a packet is invalid and dropping it, which allows remote attackers to cause a denial of service (resource exhaustion) via a flood of malformed TCP packets without any flags set.

Security readout for executives and security teams

This is an old denial-of-service issue in IBM SecureWay Firewall versions before 4.2.2. A remote attacker could send large volumes of malformed TCP traffic that the firewall spends resources processing before dropping, potentially exhausting resources and disrupting firewall availability. Exposure is most likely limited to legacy environments still running IBM SecureWay Firewall before 4.2.2, especially on internet-facing or perimeter network paths. Modern environments without this product are not exposed based on the provided sources. Treat this as a legacy perimeter-resilience risk. It is not shown as actively exploited, but any affected firewall on a critical network path could become a single point of business disruption. Mitigation focus: Identify any IBM SecureWay Firewall deployments and confirm exact versions.; Upgrade affected systems to version 4.2.2 or later where still in use.; Check IBM or successor vendor guidance for any legacy support instructions..
