Summary: This security update resolves one privately reported vulnerability in the .NET Framework. The vulnerability could allow elevation of privilege if a user views a specially crafted webpage using a web browser that can run XAML Browser Applications (XBAPs). The vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. 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.
