The PE Loader service in Microsoft .NET Framework 1.0, 1.1, and 2.0 for Windows 2000, XP, Server 2003, and Vista allows remote attackers to execute arbitrary code via unspecified vectors involving an "unchecked buffer" and unvalidated message lengths, probably a buffer overflow.

Interpretation conflict in ASP.NET in Microsoft .NET Framework 1.0, 1.1, and 2.0 for Windows 2000, XP, Server 2003, and Vista allows remote attackers to access configuration files and obtain sensitive information, and possibly bypass security mechanisms that try to constrain the final substring of a string, via %00 characters, related to use of %00 as a string terminator within POSIX functions but a data character within .NET strings, aka "Null Byte Termination Vulnerability."

The Just In Time (JIT) Compiler service in Microsoft .NET Framework 1.0, 1.1, and 2.0 for Windows 2000, XP, Server 2003, and Vista allows user-assisted remote attackers to execute arbitrary code via unspecified vectors involving an "unchecked buffer," probably a buffer overflow, aka ".NET JIT Compiler Vulnerability".

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.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, as originally demonstrated using the (1) DDS Library Shape Control (Msdds.dll) COM object, and other objects including (2) Blnmgrps.dll, (3) Ciodm.dll, (4) Comsvcs.dll, (5) Danim.dll, (6) Htmlmarq.ocx, (7) Mdt2dd.dll (as demonstrated using a heap corruption attack with uninitialized memory), (8) Mdt2qd.dll, (9) Mpg4ds32.ax, (10) Msadds32.ax, (11) Msb1esen.dll, (12) Msb1fren.dll, (13) Msb1geen.dll, (14) Msdtctm.dll, (15) Mshtml.dll, (16) Msoeacct.dll, (17) Msosvfbr.dll, (18) Mswcrun.dll, (19) Netshell.dll, (20) Ole2disp.dll, (21) Outllib.dll, (22) Psisdecd.dll, (23) Qdvd.dll, (24) Repodbc.dll, (25) Shdocvw.dll, (26) Shell32.dll, (27) Soa.dll, (28) Srchui.dll, (29) Stobject.dll, (30) Vdt70.dll, (31) Vmhelper.dll, and (32) Wbemads.dll, aka a variant of the "COM Object Instantiation Memory Corruption vulnerability."

Multiple cross-site scripting (XSS) vulnerabilities in the Mono 1.0.5 implementation of ASP.NET (.Net) allow remote attackers to inject arbitrary HTML or web script via Unicode representations for ASCII fullwidth characters that are converted to normal ASCII characters, including ">" and "<".
