MS14-009 - Important : Vulnerabilities in .NET Framework Could Allow Elevation of Privilege (2916607) - Version: 1.1

MS14-009 Version 2014-02-28 Severity Rating: Important Revision Note: V1.1 (February 28, 2014): Bulletin revised to announce a detection change in the 2901128 update for Microsoft .NET Framework 4.5.1 on Windows 8.1 for 32-bit Systems, Microsoft .NET Framework 4.5.1 on Windows 8.1 for x64-based Systems, Microsoft .NET Framework 4.5.1 on Windows Server 2012 R2, and Microsoft .NET Framework 4.5.1 on Windows RT 8.1. This is a detection change only. There were no changes to the update files. Customers who have already successfully updated their systems do not need to take any action. Summary: This security update resolves two publicly disclosed vulnerabilities and one privately reported vulnerability in Microsoft .NET Framework. The most severe vulnerability could allow elevation of privilege if a user visits a specially crafted website or a website containing specially crafted web content. In all cases, however, an attacker would have no way to force users to visit such website

Microsoft .NET Framework 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, 4.5, and 4.5.1 does not properly determine TCP connection states, which allows remote attackers to cause a denial of service (ASP.NET daemon hang) via crafted HTTP requests that trigger persistent resource consumption for a (1) stale or (2) closed connection, as exploited in the wild in February 2014, aka "POST Request DoS Vulnerability."

Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, 4.5, and 4.5.1 does not properly determine whether it is safe to execute a method, which allows remote attackers to execute arbitrary code via (1) a crafted web site or (2) a crafted .NET Framework application that exposes a COM server endpoint, aka "Type Traversal Vulnerability."

VsaVb7rt.dll in Microsoft .NET Framework 2.0 SP2 and 3.5.1 does not implement the ASLR protection mechanism, which makes it easier for remote attackers to execute arbitrary code via a crafted web site, as exploited in the wild in February 2014, aka "VSAVB7RT ASLR Vulnerability."
