Microsoft .NET Framework 4 does not properly allocate buffers, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP) or (2) a crafted .NET Framework application, aka ".NET Framework Buffer Allocation Vulnerability."

Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.0 SP2, 3.5 SP1, 3.5.1, and 4 does not properly handle an unspecified exception during use of partially trusted assemblies to serialize input data, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP) or (2) a crafted .NET Framework application, aka ".NET Framework Serialization Vulnerability."

Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.0 SP2, 3.5 SP1, 3.5.1, and 4 does not properly serialize input data, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP) or (2) a crafted .NET Framework application, aka ".NET Framework Serialization Vulnerability."

Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not properly validate function parameters, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka ".NET Framework Parameter Validation Vulnerability."

Microsoft .NET Framework 2.0 SP2 and 3.5.1 does not properly calculate the length of an unspecified buffer, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka ".NET Framework Heap Corruption Vulnerability."

Microsoft .NET Framework 2.0 SP2, 3.5.1, and 4, and Silverlight 4 before 4.1.10111, does not properly restrict access to memory associated with unmanaged objects, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, (3) a crafted .NET Framework application, or (4) a crafted Silverlight application, aka ".NET Framework Unmanaged Objects Vulnerability."

The kernel in Microsoft Windows XP SP2, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly load structured exception handling tables, which allows context-dependent attackers to bypass the SafeSEH security feature by leveraging a Visual C++ .NET 2003 application, aka "Windows Kernel SafeSEH Bypass Vulnerability."

The Forms Authentication feature in the ASP.NET subsystem in Microsoft .NET Framework 1.1 SP1, 2.0 SP2, 3.5 SP1, 3.5.1, and 4.0, when sliding expiry is enabled, does not properly handle cached content, which allows remote attackers to obtain access to arbitrary user accounts via a crafted URL, aka "ASP.NET Forms Authentication Ticket Caching Vulnerability."
