Microsoft Internet Explorer permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote HTTP servers to obtain sensitive information via a crafted document.

Microsoft Internet Explorer 5.01 SP4, 6, 6 SP1, 7, and 8 does not prevent rendering of non-HTML local files as HTML documents, which allows remote attackers to bypass intended access restrictions and read arbitrary files via vectors involving JavaScript exploit code that constructs a reference to a file://127.0.0.1 URL, aka the dynamic OBJECT tag vulnerability, as demonstrated by obtaining the data from an index.dat file, a variant of CVE-2009-1140 and related to CVE-2008-1448.

Microsoft Internet Explorer 5.01 SP4, 6, 6 SP1, 7, and 8 does not prevent rendering of non-HTML local files as HTML documents, which allows remote attackers to bypass intended access restrictions and read arbitrary files via vectors involving the product's use of text/html as the default content type for files that are encountered after a redirection, aka the URLMON sniffing vulnerability, a variant of CVE-2009-1140 and related to CVE-2008-1448.

Microsoft Internet Explorer 6, 6 SP1, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "HTML Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 6, 6 SP1, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-2530 and CVE-2009-2531.

The URL validation functionality in Microsoft Internet Explorer 5.01, 6, 6 SP1, 7 and 8, and the ShellExecute API function in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2, does not properly process input parameters, which allows remote attackers to execute arbitrary local programs via a crafted URL, aka "URL Validation Vulnerability."

Microsoft Internet Explorer 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3671.

Microsoft Internet Explorer 7 and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3674.

Microsoft Internet Explorer 6 and 7 does not properly handle objects in memory that (1) were not properly initialized or (2) are deleted, which allows remote attackers to execute arbitrary code via vectors involving a call to the getElementsByTagName method for the STYLE tag name, selection of the single element in the returned list, and a change to the outerHTML property of this element, related to Cascading Style Sheets (CSS) and mshtml.dll, aka "HTML Object Memory Corruption Vulnerability." NOTE: some of these details are obtained from third party information. NOTE: this issue was originally assigned CVE-2009-4054, but Microsoft assigned a duplicate identifier of CVE-2009-3672. CVE consumers should use this identifier instead of CVE-2009-4054.

The printing functionality in Microsoft Internet Explorer 8 allows remote attackers to discover a local pathname, and possibly a local username, by reading the dc:title element of a PDF document that was generated from a local web page.

Cross-site scripting (XSS) vulnerability in phpMyFAQ before 2.0.17 and 2.5.x before 2.5.2, when used with Internet Explorer 6 or 7, allows remote attackers to inject arbitrary web script or HTML via unspecified parameters to the search page.

Microsoft Internet Explorer 6, 6 SP1, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-2530.

Microsoft Internet Explorer 6, 6 SP1, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-2531.

Microsoft Internet Explorer 5.01 SP4, 6, 6 SP1, 7, and 8 does not properly handle argument validation for unspecified variables, which allows remote attackers to execute arbitrary code via a crafted HTML document, aka "HTML Component Handling Vulnerability."

Unspecified vulnerability in Microsoft Internet Explorer 5.01 SP4, 6, 6 SP1, and 7 allows remote attackers to execute arbitrary code via a crafted data stream header that triggers memory corruption, aka "Data Stream Header Corruption Vulnerability."

Microsoft Internet Explorer 6 on Windows XP SP2 and SP3, and Internet Explorer 7 on Vista, allows remote attackers to cause a denial of service (application crash) via JavaScript code that calls createElement to create an instance of the LI element, and then calls setAttribute to set the value attribute.

Microsoft Internet Explorer 6 through 8 allows remote attackers to spoof the address bar, via window.open with a relative URI, to show an arbitrary URL on the web site visited by the victim, as demonstrated by a visit to an attacker-controlled web page, which triggers a spoofed login form for the site containing that page.

Microsoft Internet Explorer 6 through 6.0.2900.2180 and 7 through 7.0.6000.16473 allows remote attackers to cause a denial of service (CPU consumption) via an XML document composed of a long series of start-tags with no corresponding end-tags, a related issue to CVE-2009-1232.

Cross-site scripting (XSS) vulnerability in Alt-N MDaemon WorldClient 10.0.2, when Internet Explorer 7 is used, allows remote attackers to inject arbitrary web script or HTML via a crafted img tag.
