An update that solves three vulnerabilities and has 7 fixes
is now available.

Description:

This update for xrdp fixes the following issues:

Security issues 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).

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)
