Reported : 19-Jan-2020
Fixed in iOS 13.4 with CVE-2020-9768
AppleJPEGDriverUserClient : mach port use-after-free/type-confusion via race condition 

AppleJPEGDriverUserClient external methods can be used synchronously or asynchronously, when used asynchronously, 
it brings the registered mach port (via registerNotificationPort()) and put it inside jpegRequest data structure,
and no reference count was taken for this operation. since registerNotificationPort() is not gated, it is 
possible to release the port (if the port got substituted)  during the processing of jpeg request and end up
with dangling pointer passed to _mach_msg_send_from_kernel_proper().

Installing Windows 10 "built-in" SSH Server

Starting with Windows 10 build 1709, Windows integrates a port of OpenSSH, client and server.

This note describes how to install and configure the OpenSSH server sshd and run PowerShell scripts on a remote Windows server, from a Unix system, using SSH and public key authentication (no password).

Note: The way OpenSSH has been integrated in Windows 10 has changed a lot between versions 1709 and 21H2 of Windows 10. The Gist was updated several times to reflect the changes. This version applies to Windows 10 21H2.

OpenSSH server installation
