    Its Ie - Again Again Again

    Greeting's

    Yup its IE and this thread is not about VML again.. It seems that there is a new vulnerability discovered right after VML patch came out .

    Vulnerability Note VU#753044
    Microsoft Windows WebViewFolderIcon ActiveX integer overflow


    Overview

    The Microsoft Windows WebViewFolderIcon ActiveX control contains an integer overflow vulnerability. This may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.


    I. Description
    The Microsoft WebViewFolderIcon object is an ActiveX control that comes with Microsoft Windows. This control, which is provided by the file webvw.dll, provides support functionality for icons in the Windows Explorer Web view. The slice method of the WebViewFolderIcon control contains an integer overflow vulnerability.



    II. Impact
    By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.The complete impact of this vulnerability is not yet known.
    III. Solution

    : Solution.. is there a real solution.. either disable everything or use another browser.


    Here is the solution as mentioned at the source :

    Disable the WebViewFolderIcon ActiveX control

    The WebViewFolderIcon ActiveX control can be disabled by setting the kill bit for the following CLSID:

    {844F4806-E8A8-11d2-9652-00C04FC30871}

    More information about how to set the kill bit is available in Microsoft Support Document 240797.

    Disable ActiveX

    Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this vulnerability. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document and the Malicious Web Scripts FAQ.

    Surprise, surprise. IE7 should be out soon and we'll live happily ever after.

    In fact, disabling ActiveX pretty much turns IE into a safe browser.
    I came in to the world with nothing. I still have most of it.

    Takes more than that IMO. What about Java, Scripting (JavaScript, VBScript), JVM (java virtual machine) etc...


    may also introduce vulnerabilities to the computer system
    I would recommend going here for securing your web browser.

    This has been heavily exploited over the weekend. Site all over the world are hosting exploits for the SetSlice IE vulnerability.

    SANS has a killbit app to quickly solve the issue while you wait for an MS patch.

    Eweek has a decent story on it.

    For the lazy, here is the bottom line on what's happening out there right this second. This is so massively exploited, it makes VML look cute. There's a rootkit, some other malware, and haxdor! (a phishing trojan horse).

    Although yes, there are now patches/fixes for this vulnerability, this is something that should never have been exploitable to begin with.

    There is no excuse for allowing any active scripting in the Internet Zone.


    If you are compromised, it's your own damn fault. The problem is that people remain ignorant about computers and software, even though they spend thousands of dollars to get online. When you buy a car... you figure out how to change a flat tire, or change the oil, etc. The same applies with anything, but when it comes to computers, nobody puts any effort into it.
    Real security doesn't come with an installer.
