A Buffer Error vulnerability exists in PowerSuite 2, all released versions (VW3A8104 & Patches), which could cause an overflow in the memcpy function, leading to corruption of data and program instability.

Multiple stack-based buffer overflows in ModbusDrv.exe in Schneider Electric Modbus Serial Driver 1.10 through 3.2 allow remote attackers to execute arbitrary code via a large buffer-size value in a Modbus Application Header.

Stack-based buffer overflow in Hummingbird.XWebHostCtrl.1 ActiveX control (hclxweb.dll) in Hummingbird Xweb ActiveX Control 13.0 and earlier allows remote attackers to execute arbitrary code via a long PlainTextPassword property. NOTE: code execution might not be possible in 13.0.
