This host is installed with Hyleos ChemView ActiveX Control and is prone to multiple Buffer Overflow vulnerabilities.

Successful exploitation could allow an attacker to execute arbitrary code within the context of the affected application. Impact Level: Application

No solution or patch was made available for at least one year since disclosure of this vulnerability. Likely none will be provided anymore. General solution options are to upgrade to a newer release, disable respective features, remove the product or replace the product by another one. A Workaround is to set the Killbit for the vulnerable CLSID {C372350A-1D5A-44DC-A759-767FC553D96C}

The flaws are due to two boundary errors in the 'HyleosChemView.ocx' which can be exploited to cause stack-based buffer overflows by passing strings containing an overly large number of white-space characters to the 'SaveasMolFile()' and 'ReadMolFile()' methods.

Hyleos ChemView ActiveX Control version 1.9.5.1 and prior.
