DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious people to manipulate certain data.

The vulnerability is caused due to an error in the TLS and SSL
protocols while handling session renegotiations. This can be
exploited via Man-in-the-Middle (MitM) attacks to insert arbitrary
plaintext before data sent by a legitimate client in an existing TLS
session.

This is related to:
SA37291
