SECUNIA ADVISORY ID:
SA18957

VERIFY ADVISORY:
https://secunia.com/advisories/18957/

CRITICAL:
Highly critical

IMPACT:
Spoofing, System access, Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Microsoft Internet Explorer 5.5
https://secunia.com/product/10/
Microsoft Internet Explorer 5.01
https://secunia.com/product/9/
Microsoft Internet Explorer 6.x
https://secunia.com/product/11/

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.

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.

Apply patches.
