Multiple integer overflows in setnet32.exe 3.50.0.13752 in IBM Informix Client SDK 3.0 and 3.50 and Informix Connect Runtime 3.x allow remote attackers to execute arbitrary code via a .nfx file with a crafted (1) HostSize, and possibly (2) ProtoSize and (3) ServerSize, field that triggers a stack-based buffer overflow involving a crafted HostList field. NOTE: some of these details are obtained from third party information.

Security readout for executives and security teams

This is a legacy IBM Informix client-side code execution issue. A malicious .nfx configuration file can trigger memory corruption in setnet32.exe, potentially letting an attacker run code in the user context. Business urgency depends on whether old Informix client tools are still installed and exposed to untrusted files. Exposure is most likely on legacy Windows endpoints or servers where IBM Informix Client SDK 3.0/3.50 or Informix Connect Runtime 3.x remains installed and users or workflows can open/import .nfx files from untrusted sources. Prioritize this where legacy Informix clients remain in production or on administrator workstations. If absent, risk is low. If present, treat as high-priority legacy exposure because successful exploitation could execute attacker-controlled code through file handling. Mitigation focus: Inventory systems for affected IBM Informix Client SDK and Connect Runtime versions.; Remove legacy Informix client components where no longer required.; Check IBM guidance for supported upgrades or fixed releases..
