Buffer overflow in the chunked encoding transfer mechanism in Internet Information Server (IIS) 4.0 and 5.0 Active Server Pages allows attackers to cause a denial of service or execute arbitrary code.

Cross-site scripting vulnerability in Internet Information Server (IIS) 4.0, 5.0 and 5.1 allows remote attackers to execute arbitrary script as other users via an HTTP error page.

Buffer overflow in Internet Information Server (IIS) 4.0, 5.0, and 5.1 allows remote attackers to spoof the safety check for HTTP headers and cause a denial of service or execute arbitrary code via HTTP header field values.

Buffer overflow in ssinc.dll in IIS 5.0 and 4.0 allows local users to gain system privileges via a Server-Side Includes (SSI) directive for a long filename, which triggers the overflow when the directory name is added, aka the "SSI privilege elevation" vulnerability.

Scripting.FileSystemObject in asp.dll for Microsoft IIS 4.0 and 5.0 allows local or remote attackers to cause a denial of service (crash) via (1) creating an ASP program that uses Scripting.FileSystemObject to open a file with an MS-DOS device name, or (2) remotely injecting the device name into ASP programs that internally use Scripting.FileSystemObject.

IIS 5.0 and Microsoft Exchange 2000 allow remote attackers to cause a denial of service (memory allocation error) by repeatedly sending a series of specially formatted URL's.

FrontPage Server Extensions (FPSE) in IIS 4.0 and 5.0 allows remote attackers to cause a denial of service via a malformed form, aka the "Malformed Web Form Submission" vulnerability.

Microsoft IIS for Far East editions 4.0 and 5.0 allows remote attackers to read source code for parsed pages via a malformed URL that uses the lead-byte of a double-byte character.

IIS 5.0 and 4.0 allows remote attackers to read the source code for executable web server programs by appending "%3F+.htr" to the requested URL, which causes the files to be parsed by the .HTR ISAPI extension, aka a variant of the "File Fragment Reading via .HTR" vulnerability.

Variant of the "IIS Cross-Site Scripting" vulnerability as originally discussed in MS:MS00-060 (CVE-2000-0746) allows a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site.
