Microsoft .net Framework

The default configuration of ASP.NET in Microsoft .NET before 1.1 has a value of FALSE for the EnableViewStateMac property, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the __VIEWSTATE parameter.

Buffer overflow in calloc.c in the Microsoft Windows XP SP2 ntdll.dll system library, when used by the ILDASM disassembler in the Microsoft .NET 1.0 and 1.1 SDK, might allow user-assisted attackers to execute arbitrary code via a crafted .dll file with a large static method.

ASP.NET in Microsoft .NET Framework 2.0 SP1 and SP2 and 3.5 Gold and SP1, when ASP 2.0 is used in integrated mode on IIS 7.0, does not properly manage request scheduling, which allows remote attackers to cause a denial of service (daemon outage) via a series of crafted HTTP requests, aka "Remote Unauthenticated Denial of Service in ASP.NET Vulnerability."

ASP.NET in Microsoft .NET Framework 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, 4.5, 4.5.1, and 4.5.2, when the customErrors configuration is disabled, allows remote attackers to obtain sensitive configuration-file information via a crafted request, aka "ASP.NET Information Disclosure Vulnerability."
