The Macromedia Flash ActiveX control that is provided with Windows XP contains a memory corruption vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Microsoft Windows XP provides the Macromedia Flash ActiveX control. Depending on the patch level of the system, it may be provided by either flash.ocx or flash6.ocx. This ActiveX control contains a use-after-free vulnerability, which can result in heap memory corruption. Note that this vulnerability does not affect systems that have Flash 9 or later installed, as newer versions of the Flash installer will replace the Macromedia Flash control that is provided by Windows.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code.
We are unaware of a practical solution to this problem. Please see Microsoft Security Advisory (979267) for some workarounds, including:
Disable the Flash ActiveX control in Internet Explorer
