This article describes running a commercial static source code analysis tool (Checkmarx) against the Microsoft Word 1.1a source code released by the Computer History Museum, resulting in many flagged potential vulnerabilities (buffer overflows, integer overflows, format string issues, etc.). It highlights an example unsafe strcpy usage, notes that many findings may be false positives or non-exploitable in practice, and stresses the importance of modern secure development practices (static analysis, dynamic testing, environment hardening).
