Integer overflow in GDI+ in Microsoft Internet Explorer 6 SP1, Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, Office XP SP3, Office 2003 SP2 and SP3, 2007 Microsoft Office System Gold and SP1, Visio 2002 SP2, PowerPoint Viewer 2003, Works 8, Digital Image Suite 2006, SQL Server 2000 Reporting Services SP2, SQL Server 2005 SP2, Report Viewer 2005 SP1 and 2008, and Forefront Client Security 1.0 allows remote attackers to execute arbitrary code via an image file with crafted gradient sizes in gradient fill input, which triggers a heap-based buffer overflow related to GdiPlus.dll and VGX.DLL, aka "GDI+ VML Buffer Overrun Vulnerability."

Microsoft Internet Explorer 6 and 7 accesses uninitialized memory, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via unknown vectors, aka "HTML Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01, 6, and 7 accesses uninitialized memory, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via unknown vectors, a different vulnerability than CVE-2008-2254, aka "HTML Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01, 6, and 7 does not properly handle objects that have been incorrectly initialized or deleted, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via unknown vectors, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01, 6, and 7 accesses uninitialized memory in certain conditions, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via vectors related to a document object "appended in a specific order," aka "HTML Objects Memory Corruption Vulnerability" or "XHTML Rendering Memory Corruption Vulnerability," a different vulnerability than CVE-2008-2258.

Microsoft Internet Explorer 5.01, 6, and 7 accesses uninitialized memory in certain conditions, which allows remote attackers to cause a denial of service (crash) and execute arbitrary code via vectors related to a document object "appended in a specific order" with "particular functions ... performed on" document objects, aka "HTML Objects Memory Corruption Vulnerability" or "Table Layout Memory Corruption Vulnerability," a different vulnerability than CVE-2008-2257.

Microsoft Internet Explorer 6 and 7 does not perform proper "argument validation" during print preview, which allows remote attackers to execute arbitrary code via unknown vectors, aka "HTML Component Handling Vulnerability."

Buffer overflow in the Microsoft HeartbeatCtl ActiveX control in HRTBEAT.OCX allows remote attackers to execute arbitrary code via the Host argument to an unspecified method.

The HxTocCtrl ActiveX control (hxvz.dll), as used in Microsoft Internet Explorer 5.01 SP4 and 6 SP1, in Windows XP SP2, Server 2003 SP1 and SP2, Vista SP1, and Server 2008, allows remote attackers to execute arbitrary code via malformed arguments, which triggers memory corruption.

The setRequestHeader method of the XMLHttpRequest object in Microsoft Internet Explorer 5.01, 6, and 7 does not block dangerous HTTP request headers when certain 8-bit character sequences are appended to a header name, which allows remote attackers to (1) conduct HTTP request splitting and HTTP request smuggling attacks via an incorrect Content-Length header, (2) access arbitrary virtual hosts via a modified Host header, (3) bypass referrer restrictions via an incorrect Referer header, and (4) bypass the same-origin policy and obtain sensitive information via a crafted request header.

Use-after-free vulnerability in Microsoft Internet Explorer 6 SP1, 6 SP2, and and 7 allows remote attackers to execute arbitrary code by assigning malformed values to certain properties, as demonstrated using the by property of an animateMotion SVG element, aka "Property Memory Corruption Vulnerability."

Use-after-free vulnerability in the CRecalcProperty function in mshtml.dll in Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code by calling the setExpression method and then modifying the outerHTML property of an HTML element, one variant of "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 and 7 allows remote attackers to execute arbitrary code via uninitialized or deleted objects used in repeated calls to the (1) cloneNode or (2) nodeValue JavaScript function, a different issue than CVE-2007-3902 and CVE-2007-5344, a variant of "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via a crafted website using Javascript that creates, modifies, deletes, and accesses document objects using the tags property, which triggers heap corruption, related to uninitialized or deleted objects, a different issue than CVE-2007-3902 and CVE-2007-3903, and a variant of "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via "unexpected method calls to HTML objects," aka "DHTML Object Memory Corruption Vulnerability."

The Web Proxy Auto-Discovery (WPAD) feature in Microsoft Internet Explorer 6 and 7, when a primary DNS suffix with three or more components is configured, resolves an unqualified wpad hostname in a second-level domain outside this configured DNS domain, which allows remote WPAD servers to conduct man-in-the-middle (MITM) attacks.
