History
Blue keep vulnerability is reported by UK national cyber security team on 14th may 2019.
Kevin Beaumont is named this vulnerability as a #bluekeep in this twitter page ( reference:
https://twitter.com/GossiTheDog/status/1128431661266415616 ) you can tract this officially
with CVE-2019-0708.
Microsoft says that attackers can use this vulnerability to actively propagate the worms,
similar to be eternal blue and WannaCry. Microsoft is estimated nearly 1 million devices are
vulnerable for this.

Technically The RDP protocol uses “virtual channels” configured pre-authentication, as a data path between the client and server for providing extensions. RDP 5.1 defines 32 “static” virtual channels, and “dynamic” virtual channels are contained within one of these static channels. If a server binds the virtual channel “MS_T120” (a channel for which there is no legitimate reason for a client to connect to) with a static channel other than 31, heap corruption occurs that allows for arbitrary code execution at the system level.

Microsoft released patches for the vulnerability on 13th august 2019
