CVE-2009-3691 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 7.04% chance of exploitation in the next 30 days.
