Cross-zone scripting vulnerability in the Print Table of Links feature in Internet Explorer 6.0, 7.0, and 8.0b allows user-assisted remote attackers to inject arbitrary web script or HTML in the Local Machine Zone via an HTML document with a link containing JavaScript sequences, which are evaluated by a resource script when a user prints this document.

Use-after-free vulnerability in Microsoft Internet Explorer 5.01 SP4, 6 through SP1, and 7 allows remote attackers to execute arbitrary code via a crafted data stream that triggers memory corruption, as demonstrated using an invalid MIME-type that does not have a registered handler.

Unspecified vulnerability in an ActiveX control (dxtmsft.dll) in Microsoft Internet Explorer 5.01, 6 SP1 and SP2, and 7 allows remote attackers to execute arbitrary code via a crafted image, aka "Argument Handling Memory Corruption Vulnerability."

Microsoft Internet Explorer 6.0 and 7.0 allows remote attackers to fill Zones with arbitrary domains using certain metacharacters such as wildcards via JavaScript, which results in a denial of service (website suppression and resource consumption), aka "Internet Explorer Zone Domain Specification Dos and Page Suppressing". NOTE: this issue has been disputed by a third party, who states that the zone settings cannot be manipulated

Unspecified vulnerability in Microsoft Windows 2000 SP4 through Vista allows remote attackers to execute arbitrary code or cause a denial of service (persistent reboot) via a malformed ANI file, which results in memory corruption when processing cursors, animated cursors, and icons, a similar issue to CVE-2005-0416, as originally demonstrated using Internet Explorer 6 and 7. NOTE: this issue might be a duplicate of CVE-2007-0038; if so, then use CVE-2007-0038 instead of this identifier.

Unspecified vulnerability in the CTableCol::OnPropertyChange method in Microsoft Internet Explorer 5.01 SP4 on Windows 2000 SP4; 6 SP1 on Windows 2000 SP4; and 6 on Windows XP SP2, or Windows Server 2003 SP1 or SP2 allows remote attackers to execute arbitrary code by calling deleteCell on a named table row in a named table column, then accessing the column, which causes Internet Explorer to access previously deleted objects, aka the "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01 SP4 on Windows 2000 SP4; 6 SP1 on Windows 2000 SP4; 6 and 7 on Windows XP SP2, or Windows Server 2003 SP1 or SP2; and possibly 7 on Windows Vista does not properly "instantiate certain COM objects as ActiveX controls," which allows remote attackers to execute arbitrary code via a crafted COM object from chtskdic.dll.

Multiple ActiveX controls in Microsoft Windows 2000, XP, 2003, and Vista allows remote attackers to cause a denial of service (Internet Explorer crash) by accessing the bgColor, fgColor, linkColor, alinkColor, vlinkColor, or defaultCharset properties in the (1) giffile, (2) htmlfile, (3) jpegfile, (4) mhtmlfile, (5) ODCfile, (6) pjpegfile, (7) pngfile, (8) xbmfile, (9) xmlfile, (10) xslfile, or (11) wdfile objects in (a) mshtml.dll; or the (12) TriEditDocument.TriEditDocument or (13) TriEditDocument.TriEditDocument.1 objects in (b) triedit.dll, which cause a NULL pointer dereference.

Microsoft Internet Explorer 5.01, 6, and 7 uses certain COM objects from (1) Msb1fren.dll, (2) Htmlmm.ocx, and (3) Blnmgrps.dll as ActiveX controls, which allows remote attackers to execute arbitrary code via unspecified vectors, a different issue than CVE-2006-4697.

The wininet.dll FTP client code in Microsoft Internet Explorer 5.01 and 6 might allow remote attackers to execute arbitrary code via an FTP server response of a specific length that causes a terminating null byte to be written outside of a buffer, which causes heap corruption.

Integer overflow in the Vector Markup Language (VML) implementation (vgx.dll) in Microsoft Internet Explorer 5.01, 6, and 7 on Windows 2000 SP4, XP SP2, Server 2003, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a crafted web page that contains unspecified integer properties that cause insufficient memory allocation and trigger a buffer overflow, aka the "VML Buffer Overrun Vulnerability."

Multiple unspecified vulnerabilities in DirectAnimation ActiveX controls for Microsoft Internet Explorer 5.01 through 6 have unknown impact and remote attack vectors, possibly related to (1) Danim.dll and (2) Lmrt.dll, a different set of vulnerabilities than CVE-2006-4446 and CVE-2006-4777.

Heap-based buffer overflow in the DirectAnimation Path Control (DirectAnimation.PathControl) COM object (daxctle.ocx) for Internet Explorer 6.0 SP1, on Chinese and possibly other Windows distributions, allows remote attackers to execute arbitrary code via unknown manipulations in arguments to the KeyFrame method, possibly related to an integer overflow, as demonstrated by daxctle2, and a different vulnerability than CVE-2006-4446.

Microsoft Internet Explorer 5.01, 6, and 7 uses certain COM objects from Imjpcksid.dll as ActiveX controls, which allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: this issue might be related to CVE-2006-4193.

Internet Explorer 6 on Windows XP SP2 allows remote attackers to execute arbitrary JavaScript in the context of the browser's session with an arbitrary intranet web server, by hosting script on an Internet web server that can be made inaccessible by the attacker and that has a domain name under the attacker's control, which can force the browser to drop DNS pinning and perform a new DNS query for the domain name after the script is already running.

Microsoft Internet Explorer allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code by instantiating certain Windows 2000 ActiveX COM Objects including (1) ciodm.dll, (2) myinfo.dll, (3) msdxm.ocx, and (4) creator.dll.

The Terminal Services COM object (tsuserex.dll) allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by instantiating it as an ActiveX object in Internet Explorer 6.0 SP1 on Microsoft Windows 2003 EE SP1 CN.

Microsoft Internet Explorer 6.0 SP1 and possibly other versions allows remote attackers to cause a denial of service and possibly execute arbitrary code by instantiating COM objects as ActiveX controls, including (1) imskdic.dll (Microsoft IME), (2) chtskdic.dll (Microsoft IME), and (3) msoe.dll (Outlook), which leads to memory corruption. NOTE: it is not certain whether the issue is in Internet Explorer or the individual DLL files.

Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060912, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL in a GZIP-encoded website that was the target of an HTTP redirect, due to an incomplete fix for CVE-2006-3869.

Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060824, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL on a website that uses HTTP 1.1 compression.

Integer overflow in Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a 0x7fffffff argument to the setSlice method on a WebViewFolderIcon ActiveX object, which leads to an invalid memory copy.
