    Release notes for xrdp v0.9.21 (2022/12/10)

    General announcements

    - Running xrdp and xrdp-sesman on separate hosts is still supported by this release, but is now     deprecated. This is not secure. A future v1.0 release will replace the TCP socket used between these     processes with a Unix Domain Socket, and then cross-host running will not be possible.

    Security fixes

    This update is recommended for all xrdp users and provides following important security fixes:

    - CVE-2022-23468
    - CVE-2022-23477
