Buffer overflow in the BR549.DLL ActiveX control for Internet Explorer 5.01 SP3 through 6.0 SP1 allows remote attackers to execute arbitrary code.

Internet Explorer 5.01 SP3 through 6.0 SP1 does not properly determine object types that are returned by web servers, which could allow remote attackers to execute arbitrary code via an object tag with a data parameter to a malicious file hosted on a server that returns an unsafe Content-Type, aka the "Object Type" vulnerability.

Internet Explorer 5.01 SP3 through 6.0 SP1 allows remote attackers to access and execute script in the My Computer domain using the browser cache via crafted Content-Type and Content-Disposition headers, aka the "Browser Cache Script Execution in My Computer Zone" vulnerability.

Microsoft Internet Explorer allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Internet Explorer to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.

Heap-based buffer overflow in plugin.ocx for Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to execute arbitrary code via the Load() method, a different vulnerability than CVE-2003-0115.

Internet Explorer 5.01 through 6 SP1 allows remote attackers to bypass zone restrictions and read arbitrary files via an XML object.

Internet Explorer allows remote attackers to bypass zone restrictions to inject and execute arbitrary programs by creating a popup window and inserting ActiveX object code with a "data" tag pointing to the malicious code, which Internet Explorer treats as HTML or Javascript, but later executes as an HTA application, a different vulnerability than CVE-2003-0532, and as exploited using the QHosts Trojan horse (aka Trojan.Qhosts, QHosts-1, VBS.QHOSTS, or aolfix.exe).

Internet Explorer 6 SP1 and earlier allows remote attackers to direct drag and drop behaviors and other mouse click actions to other windows by calling the window.moveBy method, aka HijackClick, a different vulnerability than CVE-2003-1027.

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.

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 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.

Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and read arbitrary files by (1) modifying the createTextRange method and using CreateLink, as demonstrated using LinkillerSaveRef, LinkillerJPU, and Linkiller, or (2) modifying the createRange method and using the FIND dialog to select text, as demonstrated using Findeath, aka the "Function Pointer Override Cross Domain" vulnerability.

Internet Explorer 5.01 through 6 allows remote attackers to spoof arbitrary web sites by injecting content from one window into another window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability. NOTE: later research shows that Internet Explorer 7 on Windows XP SP2 is also vulnerable.

Internet Explorer 6.0 SP1 and earlier, and possibly other versions, allows remote attackers to cause a denial of service (application crash from "memory corruption") via certain malformed Cascading Style Sheet (CSS) elements that trigger heap-based buffer overflows, as demonstrated using the "<STYLE>@;/" string, possibly due to a missing comment terminator that may cause an invalid length to trigger a large memory copy operation, aka the "CSS Heap Memory Corruption Vulnerability."

Integer overflow in imgbmp.cxx for Windows 2000 allows remote attackers to execute arbitrary code via a BMP image with a large bfOffBits value.

Internet Explorer for Mac 5.2.3, Internet Explorer 6 on Windows XP, and possibly other versions, does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.
