Multiple stack-based buffer overflows in the HyleosChemView.HLChemView ActiveX control (HyleosChemView.ocx) in Hyleos ChemView 1.9.5.1 allow remote attackers to execute arbitrary code via a large number of white space characters in the filename argument to the (1) SaveasMolFile and (2) ReadMolFile methods.
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.
