Cross-site scripting (XSS) vulnerability in ftp.htt in Internet Explorer 5.5 and 6.0, when running on Windows 2000 with "Enable folder view for FTP sites" and "Enable Web content in folders" selected, allows remote attackers to inject arbitrary web script or HTML via the hostname portion of an FTP URL.
Microsoft Internet Explorer 6.0 and possibly others allows remote attackers to upload arbitrary file contents when users press a key corresponding to the JavaScript (1) event.ctrlKey or (2) event.shiftKey onkeydown event contained in a webpage. NOTE: it was reported that the vendor has disputed the severity of this issue.
Internet Explorer 5.01 through 6.0 does not properly check certain parameters of a PNG file when opening it, which allows remote attackers to cause a denial of service (crash) by triggering a heap-based buffer overflow using invalid length codes during decompression, aka "Malformed PNG Image File Failure."
Internet Explorer 5.01 through 6.0 does not properly perform security checks on certain encoded characters within a URL, which allows a remote attacker to steal potentially sensitive information from a user by redirecting the user to another site that has that information, aka "Encoded Characters Information Disclosure."
Cross-site scripting vulnerability (XSS) in Internet Explorer 5.01 through 6.0 allows remote attackers to read and execute files on the local system via web pages using the <frame> or <iframe> element and javascript, aka "Frames Cross Site Scripting," as demonstrated using the PrivacyPolicy.dlg resource.
Internet Explorer 5.01 through 6.0 allows remote attackers to identify the path to the Temporary Internet Files folder and obtain user information such as cookies via certain uses of the OBJECT tag, which are not subjected to the proper security checks, aka "Temporary Internet Files folders Name Reading."
Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model and access information on the local system or in other domains, and possibly execute code, via cached methods and objects, aka "Cross Domain Verification via Cached Methods."
Heap-based buffer overflow in the Remote Data Services (RDS) component of Microsoft Data Access Components (MDAC) 2.1 through 2.6, and Internet Explorer 5.01 through 6.0, allows remote attackers to execute code via a malformed HTTP request to the Data Stub.
Cross-Frame scripting vulnerability in the WebBrowser control as used in Internet Explorer 5.5 and 6.0 allows remote attackers to execute arbitrary code, read arbitrary files, or conduct other unauthorized activities via script that accesses the Document property, which bypasses <frame> and <iframe> domain restrictions.
