Release notes for xrdp v0.9.23 (2023/08/31) General announcements - Running
xrdp and xrdp-sesman on separate hosts is still supported by this release, but

cross-host running will not be possible. Security fixes - CVE-2023-40184:
Improper handling of session establishment errors allows bypassing OS-level
session restrictions (Reported by @gafusss) Bug fixes - Environment variables
set by PAM modules are no longer restricted to around 250 characters (#2712) -
X11 clipboard clients now no longer hang when requesting a clipboard format
which isn't available (#2767) New features No new features in this release.
Internal changes - Introduce release tarball generation script (#2703) -
cppcheck version used for CI bumped to 2.11 (#2738) Known issues - On-the-fly
resolution change requires the Microsoft Store version of Remote Desktop client
but sometimes crashes on connect (#1869) - xrdp's login dialog is not relocated
at the center of the new resolution after on-the-fly resolution change happens
