DESCRIPTION:
Two vulnerabilities have been reported in Microsoft .NET Framework
and Microsoft Silverlight, which can be exploited by malicious people
to compromise a user's system.

1) An unspecified error when handling un-managed objects can be
exploited via e.g. a specially crafted XAML Browser Application
(XBAP).

2) An error when calculating certain buffer lengths can be exploited
to corrupt memory via e.g. a specially crafted XAML Browser
Application (XBAP).

Successful exploitation of the vulnerabilities allows execution of
arbitrary code, but requires a browser that can run a XAML Browser
Application (XBAP) or Silverlight application.

SOLUTION:
Apply patches.
