4 new vulnerabilities found in Internet Explorer
Quote:
1) It is possible to redirect a function to another function with the same name, which allows a malicious website to access the function without the normal security restrictions.
Successful exploitation allows execution of arbitrary script code in the context of another website. This could potentially allow execution of arbitrary code in other security zones too.
2) Malicious sites can trick users into performing actions like drag'n'drop or click on a resource without their knowledge. An example has been provided, which allows sites to add links to "Favorites". However, resources need not be links and the destination could be different than "Favorites".
This issue is a variant of an issue discovered by Liu Die Yu.
SA9711
http-equiv has posted a PoC (Proof of Concept), which combined with the inherently insecure Windows "shell:" functionality, can be exploited to compromise a vulnerable system.
3) It is possible to inject arbitrary script code into Channel links in Favorites, which will be executed when the Channel is added. The script code is executed in Local Security Zone context.
4) It is possible to place arbitrary content above any other window and dialog box using the "Window.createPopup()" function. This can be exploited to "alter" the appearance of dialog boxes and other windows.
