Microsoft Internet Explorer 8 and earlier, and Internet Explorer 9 beta, does not properly restrict cross-zone drag-and-drop actions, which allows user-assisted remote attackers to read cookie files via vectors involving an IFRAME element with a SRC attribute containing a file: URL, as demonstrated by a Facebook game, related to a "cookiejacking" issue.
The CLSIDApprenticeICW control allows remote attackers to cause a denial of service (Internet Explorer crash) by creating a COM object of the class associated with the control's CLSID, which is not intended for use within Internet Explorer.
Microsoft Internet Explorer 6 through 9, and 10 Consumer Preview, allows remote attackers to bypass Protected Mode or cause a denial of service (memory corruption) by leveraging access to a Low integrity process, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012.
The System Monitor Source Properties control allows remote attackers to cause a denial of service (Internet Explorer crash) by creating a COM object of the class associated with the control's CLSID, which is not intended for use within Internet Explorer.
Microsoft Internet Explorer 6 does not properly handle errors related to using the componentFromPoint method on xml objects that have been (1) incorrectly initialized or (2) deleted, which allows remote attackers to execute arbitrary code via a crafted HTML document, aka "Uninitialized Memory Corruption Vulnerability."
Cross-zone scripting vulnerability in the Print Table of Links feature in Internet Explorer 6.0, 7.0, and 8.0b allows user-assisted remote attackers to inject arbitrary web script or HTML in the Local Machine Zone via an HTML document with a link containing JavaScript sequences, which are evaluated by a resource script when a user prints this document.
The setRequestHeader method of the XMLHttpRequest object in Microsoft Internet Explorer 7 does not restrict the dangerous Transfer-Encoding HTTP request header, which allows remote attackers to conduct HTTP request splitting and HTTP request smuggling attacks via a POST containing a "Transfer-Encoding: chunked" header and a request body with an incorrect chunk size.
Microsoft Internet Explorer 6 through 6.0.2900.2180 and 7 through 7.0.6000.16711 allows remote attackers to cause a denial of service (application hang) via a JavaScript loop that configures the home page by using the setHomePage method and a DHTML behavior property.
Microsoft Internet Explorer 6 through 6.0.2900.2180, and 7.0.6000.16711, allows remote attackers to cause a denial of service (CPU consumption) via an automatically submitted form containing a KEYGEN element, a related issue to CVE-2009-1828.
Microsoft Internet Explorer 7 through 7.0.6000.16711 allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.
Stack-based buffer overflow in the AddFavorite method in Microsoft Internet Explorer allows remote attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a long URL in the first argument.
