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 5.01 SP4, 6, 6 SP1, and 7 does not properly handle unspecified "encoding strings," which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted web site, aka "Post Encoding Information Disclosure Vulnerability."

Use-after-free vulnerability in Microsoft Internet Explorer 5.01 SP4, 6, and 6 SP1 allows remote attackers to execute arbitrary code by changing unspecified properties of an HTML object that has an onreadystatechange event handler, aka "HTML Object Memory Corruption Vulnerability."

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 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 5.01 SP4, 6, and 6 SP1 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 6, 6 SP1, and 7 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 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 Tabular Data Control (TDC) ActiveX control in Microsoft Internet Explorer 5.01 SP4, 6 on Windows XP SP2 and SP3, and 6 SP1 allows remote attackers to execute arbitrary code via a long URL (DataURL parameter) that triggers memory corruption in the CTDCCtl::SecurityCHeckDataURL function, aka "Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 SP1 and SP2, 7, and 8 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 6 SP1 and SP2, 7, and 8 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, related to the CStyleSheet object and a free of the root container, aka "Memory Corruption Vulnerability."

Microsoft Internet Explorer before 8 uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.

The JavaScript implementation in Microsoft Internet Explorer 8.0 and earlier does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.

Microsoft Internet Explorer allows remote attackers to cause a denial of service (crash) via an IFRAME with a certain XML file and XSL stylesheet that triggers a crash in mshtml.dll when a refresh is called, probably a null pointer dereference.

The Cascading Style Sheets (CSS) implementation in Microsoft Internet Explorer 8.0 and earlier does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.

Heap-based buffer overflow in the Hrtbeat.ocx (Heartbeat) ActiveX control for Internet Explorer 5.01 through 6, when users who visit online gaming sites that are associated with MSN, allows remote attackers to execute arbitrary code via the SetupData parameter.

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.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by setting the location or URL property of a MHTMLFile ActiveX object.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by accessing the object references of a FolderItem ActiveX object, which triggers a null dereference in the security check.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (stack overflow exception) via a DXImageTransform.Microsoft.Gradient ActiveX object with a long (1) StartColorStr or (2) EndColorStr property.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by setting the Filter property of an ADODB.Recordset ActiveX object to certain values multiple times, which triggers a null dereference.

Heap-based buffer overflow in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allows remote attackers to execute arbitrary code via crafted UTF-8 encoded HTML that results in size discrepancies during conversion to Unicode, aka "HTML Decoding Memory Corruption Vulnerability."
