Microsoft Internet Explorer SVG animateMotion.by Code Execution
Vulnerability
------------------------------------------------------------------------


SUMMARY

A vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Internet Explorer. User interaction
is required to exploit this vulnerability in that the target must visit a
malicious page.

DETAILS

The specific flaw exists in the handling of the "by" property of an
animateMotion SVG element. By assigning other DOM elements to this
property, a memory corruption occurs during the destruction of a Variant
data type. The corruption causes an overwrite of a virtual function
address allowing for the execution of arbitrary code.
