DESCRIPTION:
A vulnerability has been reported in Microsoft .NET Framework, which
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error within the .NET CRL
(Common Language Runtime) when handling certain parameters passed to
a function and can be exploited via a specially crafted web page.

Successful exploitation allows execution of arbitrary code, but
requires a browser that can run XAML Browser Applications (XBAPs).

SOLUTION:
Apply patches.
