Internet Explorer

Microsoft Internet Explorer 6 and 7 Beta 2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a certain createTextRange call on a checkbox object, which results in a dereference of an invalid table pointer.Show less

Buffer overflow in the IsComponentInstalled method in Internet Explorer 6.0, when used on Windows 2000 before SP4 or Windows XP before SP1, allows remote attackers to execute arbitrary code via JavaScript that calls IsComponentInstalled with a long first argument.Show less

The scripting engine in Internet Explorer allows remote attackers to cause a denial of service (resource consumption) and possibly execute arbitrary code via a web page that contains a recurrent call to an infinite loop in Javascript or VBscript, which consumes the stack, as demonstrated by resetting the "location" variable within the loop.Show less

Microsoft Internet Explorer allows remote attackers to spoof a legitimate URL in the status bar and conduct a phishing attack via a web page with an anchor element with a legitimate "href" attribute, a form whose action points to a malicious URL, and an INPUT submit element that is modified to look like a legitimate URL. NOTE: this issue is very similar to CVE-2004-1104, although the manipulations are slightly different.Show less

jscript.dll in Microsoft Internet Explorer 6.0 SP1 and earlier allows remote attackers to cause a denial of service (application crash) via a Shockwave Flash object that contains ActionScript code that calls VBScript, which in turn calls the Javascript document.write function, which triggers a null dereference.Show less

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to bypass the Kill bit settings for dangerous ActiveX controls via unknown vectors involving crafted HTML, which can expose the browser to attacks that would otherwise be prevented by the Kill bit setting. NOTE: CERT/CC claims that MS05-054 fixes this issue, but it is not described in MS05-054.Show less

The CLSID_ApprenticeICW 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.Show less

The SmartConnect Class 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.Show less

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.Show less

The Outlook Progress Ctl 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.Show less

Internet Explorer 6.0, and possibly other versions, allows remote attackers to bypass the same origin security policy and make requests outside of the intended domain by calling open on an XMLHttpRequest object (Microsoft.XMLHTTP) and using tab, newline, and carriage return characters within the first argument (method name), which is supported by some proxy servers that convert tabs to spaces. NOTE: this issue can be leveraged to conduct referer spoofing, HTTP Request Smuggling, and other attacks.Show less

Microsoft Internet Explorer 6.0 on Windows NT 4.0 SP6a, Windows 2000 SP4, Windows XP SP1, Windows XP SP2, and Windows Server 2003 SP1 allows remote attackers to cause a denial of service (client crash) via a certain combination of a malformed HTML file and a CSS file that triggers a null dereference, probably related to rendering of a DIV element that contains a malformed IMG tag, as demonstrated by IEcrash.htm and IEcrash.rar.Show less

Race condition in Microsoft Internet Explorer allows user-assisted attackers to overwrite arbitrary files and possibly execute code by tricking a user into performing a drag-and-drop action from certain objects, such as file objects within a folder view, then predicting the drag action, and re-focusing to a malicious window.Show less

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, aka a variant of the "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2127.Show less

Microsoft Internet Explorer 5.01, 5.5, and 6, when using an HTTPS proxy server that requires Basic Authentication, sends URLs in cleartext, which allows remote attackers to obtain sensitive information, aka "HTTPS Proxy Vulnerability."Show less

Multiple design errors in Microsoft Internet Explorer 5.01, 5.5, and 6 allow user-assisted attackers to execute arbitrary code by (1) overlaying a malicious new window above a file download box, then (2) using a keyboard shortcut and delaying the display of the file download box until the user hits a shortcut that activates the "Run" button, aka "File Download Dialog Box Manipulation Vulnerability."Show less

Microsoft Internet Explorer allows remote attackers to bypass cross-domain security restrictions and obtain sensitive information by using the @import directive to download files from other domains that are not valid Cascading Style Sheets (CSS) files, as demonstrated using Google Desktop, aka "CSSXSS" and "CSS Cross-Domain Information Disclosure Vulnerability."Show less

The HTML rendering engine in Microsoft Internet Explorer 6.0 allows remote attackers to conduct cross-site scripting (XSS) attacks via HTML in corrupted images and other files such as .GIF, JPG, and WAV, which is rendered as HTML when the user clicks on the link, even though the web server response and file extension indicate that it should be treated as a different file type.Show less

Internet Explorer 5.0, 5.5, and 6.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, including (1) devenum.dll, (2) diactfrm.dll, (3) wmm2filt.dll, (4) fsusd.dll, (5) dmdskmgr.dll, (6) browsewm.dll, (7) browseui.dll, (8) shell32.dll, (9) mshtml.dll, (10) inetcfg.dll, (11) infosoft.dll, (12) query.dll, (13) syncui.dll, (14) clbcatex.dll, (15) clbcatq.dll, (16) comsvcs.dll, and (17) msconf.dll, which causes memory corruption, aka "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2087.Show less
