# Release notes for xrdp v0.9.19 (2022/03/17)
## 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 release will replace the TCP socket used between these processes with a Unix Domain Socket, and then cross-host running will not be possible.
## New features
* Both inbound and outbound clipboards can now be restricted for text, files or images [Sponsored by @CyberTrust @clear-code and @kenhys] (#2087)
## Bug fixes
* [CVE-2022-23613](https://www.cve.org/CVERecord?id=CVE-2022-23613): Privilege escalation on xrdp-sesman (This fix is also in the out-of-band v0.9.18.1 release)
* The versions of imlib2 used on RHEL 7 and 8 are now detected correctly (#2118)
* Some situations where zombie processes could exist have been resolved (#2146, #2151, #2168)
* Some null-pointer exceptions which can happen in the logging module have been addressed (#2149)
* Some minor logging errors have been corrected (#2152)
* The signal handling in sesman has been reworked to prevent race conditions when a child exits. This has also made it possible to reliably reload the sesman configuration with SIGHUP (#1729, #2168)
## Internal changes
* Versions 0.13 and later of checklib can undefine the pre-processor symbol `HAVE_STDINT_H`. The xrdp tests now build successfully against these versions (#2124)
* OpenSSL packaging changes (#2130):-
- The OpenSSL 3 EVP interface is now fully supported
- When building against OpenSSL 3, an internal implementation of the RC4 cipher is used instead of the implementation from the OpenSSL legacy provider
- The wrapping of the OpenSSL library has been improved which should make it simpler to provide an alternative cryptographic provider in the future, if required
- The logging of TLS/non-TLS security negotiation has been improved
* cppcheck version used for CI bumped to 2.7 (#2140)
* The `s_check()` macro which is easily mis-used has been removed (#2144)
* Status values for the DRDYNVC channel are now available in `libxrdp/xrdp_channel.h`
## Changes for packagers or developers
* On OpenSSL 3 systems, there is now no need to build with the `-Wno-error=deprecated-declarations` flag
## 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 (#1867)
-----------------------
# Release notes for xrdp v0.9.18.1 (2022/02/08)
This is a security fix release that includes fixes for the following privilege escalation vulnerability.
* [CVE-2022-23613: Privilege escalation on xrdp-sesman](https://www.cve.org/CVERecord?id=CVE-2022-23613)
Users who uses xrdp v0.9.17 or v0.9.18 are recommended to update to this version.
## Special thanks
Thanks to [Gilad Kleinman](https://github.com/giladkl) reporting the vulnerability and reviewing fix.

# Release notes for xrdp v0.9.18 (2022/01/10)
## 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 release will replace the TCP socket used between these processes with a Unix Domain Socket, and then cross-host running will not be possible.
* Special thanks for @trishume for contributing code to the RFX codec
## New features
* Backgrounds and logos on the login screen can now be zoomed and scaled (#1962)
* Small change for Alpine Linux support (#2005)

* Logging is improved for security protocol level decisions (#1974, #1975)
* An unnecessary log error message which is always generated when running neutrinordp has been removed (#2016)
* An incorrect development log message has been fixed (#2074)
* Some informational and error messages written to the console on stdout have been removed or replaced with log messages (#2078 #2080)

* Remote drive redirection now works if printer redirection is also requested by the client (#327)
* Some file names could not be copied from the client to the server over the clipboard. This is now fixed (#1992, #1995)
* A config value has been added which allows copy-pasting of files to work with Nautilus for GNOME 3 versions >= 3.29.92 (#1994, #1996)
* Clipboard now works properly when files can't be read (#1997 #2001)
* (xorgxrdp v0.2.18) The screen is fully refreshed after initialising shared memory which should fix black screen problems like #1964
* An incorrect initialisation reported by @qarmin has been fixed (#1909)
* Some minor memory leaks have been fixed (#2014 #2028)
* A hard hang in chansrv when copying files from the remote system has been addressed (#2032)
* Users can now capitalise username and password on the login screen if required (#2061)
* Some failed size checks in the fastpath code with `--enable-devel-streamcheck` have been addressed (#2066,#2070)
* Log level for clipboard restriction has been promoted from DEVEL DEBUG to INFO (#2088)
* A buffer overflow in the RFX codec associated with large screens has been fixed (#2087)
## Internal changes

* A compiler warning with -O3 on gcc 11.1 has been addressed (#2105)
* An unused declaration for xrdp_wm_drdynvc_up has been removed (#2098)
* The SCP V0 code has been unified, which will make it easier to update and replace (#2011)
* Monitor processing unit tests for existing xrdp_sec function have been added (#1932)
* The librfxcodec has been updated as part of #2087, and also to add stack frames to assemble code to assist debugging
## Changes for packagers or developers
* The `--with-imlib2` option has been added. If xrdp is built with imlib2, the login screen supports more image formats for the background and logo, and better quality zooming and scaling (#1962)
## 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 (#1867)

# Release notes for xrdp v0.9.8 (2018/09/25)
## Deprecation notice
We removed TLSv1 and TLSv1.1 from the default config. The current default is TLSv1.2
and TLSv1.3. Users can whenever re-enable these early TLS versions by editing xrdp.
To use TLSv1.3, OpenSSL or LibreSSL must support TLSv1.3. You can know the OpenSSL
or LibreSSL version by `xrdp --version` command that compiled with xrdp.
## Other topics
Pulseaudio modules has been removed from xrdp source tree since it is actually
independent and not part of xrdp. The repository has been moved to:

## Compatibility notice
Exclamation mark (`!`) has been removed from comment out symbol of config files.
Use number sign (`#`) or semicolon (`;`) instead. As a result of this change, now
you can use exclamation mark as config value such as in `tls_ciphers`.
```
tls_ciphers=HIGH:!aNULL:!eNULL:!EXPORT:!RC4
```
