Microsoft Internet Explorer 6.0

Internet Explorer 5.x and 6.0 allows remote attackers to execute arbitrary programs via a modified directory traversal attack using a URL containing ".." (dot dot) sequences and a filename that ends in "::" which is treated as a .chm file even if it does not have a .chm extension. NOTE: this bug may overlap CVE-2004-0475.

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.

Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions by (1) using the NavigateAndFind method to load a file: URL containing Javascript, as demonstrated by NAFfileJPU, (2) using the window.open method to load a file: URL containing Javascript, as demonstrated using WsOpenFileJPU, (3) setting the href property in the base tag for the _search window, as demonstrated using WsBASEjpu, (4) loading the search window into an Iframe, as demonstrated using WsFakeSrc, (5) caching a javascript: URL in the browser history, then accessing that URL in the same frame as the target domain, as demonstrated using WsOpenJpuInHistory, NAFjpuInHistory, BackMyParent, BackMyParent2, and RefBack, aka the "Script URLs Cross Domain" vulnerability.

Microsoft Internet Explorer 6.0 SP1 and possibly other versions allows remote attackers to cause a denial of service and possibly execute arbitrary code by instantiating COM objects as ActiveX controls, including (1) imskdic.dll (Microsoft IME), (2) chtskdic.dll (Microsoft IME), and (3) msoe.dll (Outlook), which leads to memory corruption. NOTE: it is not certain whether the issue is in Internet Explorer or the individual DLL files.

Heap-based buffer overflow in HTML Help ActiveX control (hhctrl.ocx) in Microsoft Internet Explorer 6.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code by repeatedly setting the Image field of an Internet.HHCtrl.1 object to certain values, possibly related to improper escaping and long strings.

Microsoft Internet Explorer 5.01 and 6.0 allow remote attackers to execute arbitrary code via malformed Content-Disposition and Content-Type header fields that cause the application for the spoofed file type to pass the file back to the operating system for handling rather than raise an error message, aka the first variant of the "Content Disposition" vulnerability.

Internet Explorer 5.5 and 6.0 allows remote attackers to cause the File Download dialogue box to misrepresent the name of the file in the dialogue in a way that could fool users into thinking that the file type is safe to download.

Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and execute Javascript by setting the window's "href" to the malicious Javascript, then calling execCommand("Refresh") to refresh the page, aka BodyRefreshLoadsJPU or the "ExecCommand Cross Domain" vulnerability.

Internet Explorer 5.01 through 6.0 does not properly handle object tags returned from a Web server during XML data binding, which allows remote attackers to execute arbitrary code via an HTML e-mail message or web page.

Mozilla Firefox 0.9.2 allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk, and .sch.uk, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session. NOTE: it was later reported that 2.x is also affected.

Microsoft Internet Explorer 5.01 and 6.0 allow remote attackers to execute arbitrary code via malformed Content-Disposition and Content-Type header fields that cause the application for the spoofed file type to pass the file back to the operating system for handling rather than raise an error message, aka the second variant of the "Content Disposition" vulnerability.
