"This update for xrdp fixes the following issues :

These security issues were fixed :

CVE-2013-1430: When successfully logging in using RDP into an xrdp
session, the file ~/.vnc/sesman_${username}_passwd was created. Its
content was the equivalent of the user's cleartext password, DES
encrypted with a known key (bsc#1015567).

CVE-2017-16927: The scp_v0s_accept function in
sesman/libscp/libscp_v0.c in the session manager in xrdp through used
an untrusted integer as a write length, which could lead to a local
denial of service (bsc#1069591).

CVE-2017-6967: Fixed call of the PAM function auth_start_session().
This lead to to PAM session modules not being properly initialized,
with a potential consequence of incorrect configurations or elevation
of privileges, aka a pam_limits.so bypass (bsc#1029912).

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"WARNING: Please note that this update comes with a slightly different
syntax of sesman.ini file, so if you edited this file by hand, you may
need to look at the .rpmnew file and merge any required changes by
hand.

This release also creates three files in /etc/xrdp directory if they
don't already exist or are empty :

  - rsakeys.ini

  - cert.pem

  - key.pem

Also note that in Fedora, the only backend that will really work is
still Xvnc for now.

New features

  - New xorgxrdp backend using existing Xorg with additional
    modules

  - Improvements to X11rdp backend

  - Support for IPv6 (disabled by default)

  - Initial support for RemoteFX Codec (disabled by default)

  - Support for TLS security layer (preferred over RDP layer
    if supported by the client)

  - Support for disabling deprecated SSLv3 protocol and for
    selecting custom cipher suites in xrdp.ini

  - Support for bidirectional fastpath (enabled in both
    directions by default)

  - Support clients that don't support drawing orders, such
    as MS RDP client for Android, ChromeRDP (disabled by
    default)

  - More configurable login screen

  - Support for new virtual channels :

    - rdpdr: device redirection

    - rdpsnd: audio output

    - cliprdr: clipboard

    - xrdpvr: xrdp video redirection channel (can be used
      along with NeutrinoRDP client)

  - Support for disabling virtual channels globally or by
    session type

  - Allow to specify the path for backends (Xorg, X11rdp,
    Xvnc)

  - Added files for systemd support

  - Multi-monitor support

  - xrdp-chansrv stroes logs in ${XDG_DATA_HOME}/xrdp now

Security fixes

  - User's password could be recovered from the Xvnc
    password file

  - X11 authentication was not used

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as

Other issues addressed: The KillDisconnected option for TigerVNC Xvnc
sessions is now supported (bsc#1101506)

Fixed an issue with delayed X KeyRelease events (bsc#1100453)

Force xrdp-sesman.service to start after xrdp.service. (bsc#1014524)

Avoid use of hard-coded sesman port. (bsc#1060644)

Backport upstream commit 5575197, sesman should stop setting LANG and
let initialization scripts take care of it (bsc#1023988).

Backport upstream patches for 32bpp support (bsc#1022098).

Fixed a regression connecting from Windows 10. (bsc#1090174)

"WARNING: Please note that this update comes with a slightly different
syntax of sesman.ini file, so if you edited this file by hand, you may
need to look at the .rpmnew file and merge any required changes by
hand.

This release also creates three files in /etc/xrdp directory if they
don't already exist or are empty :

  - rsakeys.ini

  - cert.pem

  - key.pem

Also note that in Fedora, the only backend that will really work is
still Xvnc for now.

New features

  - New xorgxrdp backend using existing Xorg with additional
    modules

  - Improvements to X11rdp backend

  - Support for IPv6 (disabled by default)

  - Initial support for RemoteFX Codec (disabled by default)

  - Support for TLS security layer (preferred over RDP layer
    if supported by the client)

  - Support for disabling deprecated SSLv3 protocol and for
    selecting custom cipher suites in xrdp.ini

  - Support for bidirectional fastpath (enabled in both
    directions by default)

  - Support clients that don't support drawing orders, such
    as MS RDP client for Android, ChromeRDP (disabled by
    default)

  - More configurable login screen

  - Support for new virtual channels :

    - rdpdr: device redirection

    - rdpsnd: audio output

    - cliprdr: clipboard

    - xrdpvr: xrdp video redirection channel (can be used
      along with NeutrinoRDP client)

  - Support for disabling virtual channels globally or by
    session type

  - Allow to specify the path for backends (Xorg, X11rdp,
    Xvnc)

  - Added files for systemd support

  - Multi-monitor support

  - xrdp-chansrv stroes logs in ${XDG_DATA_HOME}/xrdp now

Security fixes

  - User's password could be recovered from the Xvnc
    password file

  - X11 authentication was not used

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
