The CERT Coordination Center at the Carnegie Mellon Software Engineering Institute in Pittsburgh on Thursday released a free, open-source tool that software developers can use to detect ActiveX vulnerabilities. Dubbed Dranzer, the tool was tested on 22,000 ActiveX controls produced by more than 5,000 organizations. Dranzer is designed for use during the quality assurance phase of software creation and can help prevent flaws, such as buffer overflows, from being shipped in software to the public. — DK
