Description:
Multiple vulnerabilities have been reported in Internet Explorer, which can be exploited by malicious people to conduct cross-site scripting attacks, conduct phishing attacks, or compromise a user's system.
1) An error in the cross-domain restriction when accessing properties of certain dynamically created objects can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an arbitrary site via a JavaScript URI handler applied on a dynamically created "object" tag.
2) An error within the handling of multiple event handlers (e.g. onLoad) in an HTML element can be exploited to corrupt memory in a way that may allow execution of arbitrary code.
For more information:
SA19269
3) An error within the parsing of specially crafted, non-valid HTML can be exploited to corrupt memory in a way that allows execution of arbitrary code when a malicious HTML document is viewed.
4) An error within the instantiation of COM objects that are not intended to be instantiated in Internet Explorer can be exploited to corrupt memory in a way that allows execution of arbitrary code.
5) An error within the handling of HTML elements containing a specially crafted tag can be exploited to corrupt memory in a way that allows execution of arbitrary code.
6) An error within the handling of double-byte characters in specially crafted URLs can be exploited to corrupt memory in a way that allows execution of arbitrary code.
Successful exploitation requires that the system uses double-byte character sets.
7) An error in the way IOleClientSite information is returned when an embedded object is dynamically created can be exploited to execute arbitrary code in context of another site or security zone.
8) An unspecified error can be exploited to spoof information displayed in the address bar and other parts of the trust UI.
9) Some unspecified vulnerabilities exist in the two ActiveX controls included with Danim.dll and Dxtmsft.dll.
