The description on Microsoft's Knowledge Base adds that the security bulletin "addresses a defense-in-depth update for the secdrv.sys driver, a third-party driver" by turning the service for the driver off. The security bulletin itself mentions that the update resolves vulnerabilities in Microsoft Windows, Microsoft Office and Lync which attackers could exploit to run code remotely on affected systems. These are all old games released more than 10 years ago but still playable on modern systems. Games that rely on Safedisc include the Age of Empire series, Battlefield 1942, Civilization 3, various Command and Conquer games or Microsoft Flight Simulator.
