Revision Note: V2.1 (February 12, 2013): Bulletin revised to announce a detection change in the .NET Framework 1.1 Service Pack 1 update (KB2742597) to correct a Windows Update reoffering issue on certain systems that are running supported editions of Windows Vista or Windows Server 2008. This is a detection change only. Customers who have already successfully updated their systems do not need to take any action.
Summary: This security update resolves four privately reported vulnerabilities in the .NET Framework. The most severe of these vulnerabilities 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 vulnerabilities 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 logged-on 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.Other versions
