MS12-072  Vulnerabilities in Windows Shell Could Allow Remote Code Execution

2012-11-13 This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution if a user browses to a specially crafted briefcase in Windows Explorer. An attacker who successfully exploited the vulnerabilities could run arbitrary code as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
