Buffer overflow in the Steema TeeChart ActiveX control, as used in Schneider Electric Vijeo Historian 4.30 and earlier, CitectHistorian 4.30 and earlier, and CitectSCADAReports 4.10 and earlier, allows remote attackers to execute arbitrary code or cause a denial of service via unspecified vectors.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
