danim.dll in Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (application crash) by accessing the Data property of a DirectAnimation DAUserData object before it is initialized, which triggers a NULL pointer dereference.
Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) by setting the fonts property of the HtmlDlgSafeHelper object, which triggers a null dereference.
Internet Explorer 6 on Windows XP allows remote attackers to cause a denial of service (crash) by setting the Enabled property of a DXTFilter ActiveX object to true, which triggers a null dereference.
Microsoft Internet Explorer 6.0 and 6.0 SP1 allows remote attackers to cause a denial of service via an HTML page with an A tag containing a long title attribute. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by declaring the sourceURL attribute on an uninitialized DirectAnimation.StructuredGraphicsControl ActiveX Object, which triggers a null dereference.
Heap-based buffer overflow in HTML Help ActiveX control (hhctrl.ocx) in Microsoft Internet Explorer 6.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code by repeatedly setting the Image field of an Internet.HHCtrl.1 object to certain values, possibly related to improper escaping and long strings.
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.
Cross-domain vulnerability in Microsoft Internet Explorer 6.0 allows remote attackers to access restricted information from other domains via an object tag with a data parameter that references a link on the attacker's originating site that specifies a Location HTTP header that references the target site, which then makes that content available through the outerHTML attribute of the object, aka "Redirect Cross-Domain Information Disclosure Vulnerability."
Microsoft Internet Explorer 6.0 does not properly handle Drag and Drop events, which allows remote user-assisted attackers to execute arbitrary code via a link to an SMB file share with a filename that contains encoded ..\ (%2e%2e%5c) sequences and whose extension contains the CLSID Key identifier for HTML Applications (HTA), aka "Folder GUID Code Execution Vulnerability." NOTE: directory traversal sequences were used in the original exploit, although their role is not clear.
Multiple unspecified vulnerabilities in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allow remote attackers to execute arbitrary code by instantiating certain COM objects from Wmm2fxa.dll as ActiveX controls including (1) DXImageTransform.Microsoft.MMSpecialEffect1Input, (2) DXImageTransform.Microsoft.MMSpecialEffect1Input.1, (3) DXImageTransform.Microsoft.MMSpecialEffect2Inputs, (4) DXImageTransform.Microsoft.MMSpecialEffect2Inputs.1, (5) DXImageTransform.Microsoft.MMSpecialEffectInplace1Input, and (6) DXImageTransform.Microsoft.MMSpecialEffectInplace1Input.1, which causes memory corruption during garbage collection.
