DESCRIPTION:
Multiple vulnerabilities have been reported in Microsoft .NET
Framework, which can be exploited by malicious people to bypass
certain security restrictions and compromise a user's system.

1) An error within the System Drawing namespace of Windows Forms when
handling pointers can be exploited to bypass CAS (Code Access
Security) restrictions and disclose information via a specially
crafted XAML Browser Application (XBAP) or an untrusted .NET
application.

2) An error within WinForms when handling certain objects can be
exploited to cause a buffer overflow via a specially crafted XAML
Browser Application (XBAP) or an untrusted .NET application.

3) A boundary error within the System.DirectoryServices.Protocols
namespace when handling objects can be exploited to cause a buffer
overflow via a specially crafted XAML Browser Application (XBAP) or
an untrusted .NET application.

4) A double construction error within the framework does not validate
object permissions and can be exploited via a specially crafted XAML
Browser Application (XBAP) or an untrusted .NET application.

Successful exploitation of vulnerabilities #2 - #4 allows execution
of arbitrary code.

SOLUTION:
Apply updates.
