"The version of Microsoft Silverlight installed on the remote host
reportedly incorrectly checks a memory pointer when rendering an HTML
object, which could allow a specially crafted application to access
memory in an unsafe fashion.

If an attacker could trick a user on the affected system into visiting a
website hosting a malicious Silverlight application, the attacker could
leverage this vulnerability to execute arbitrary code on the affected
system, subject to the user's privileges."
