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

The vulnerability is caused due to an error in Windows OLE Dialog
components handling of OLE objects in RTF (Rich Text Format) files.
This can be exploited to cause a memory corruption by e.g. tricking a
user into opening a malicious RTF document using Wordpad and interact
with a specially crafted embedded OLE object.

Successful exploitation allows execution of arbitrary code.
