   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
   - 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
   - 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 bypass (bsc#1029912).

   These non-security issues were fixed:

   - The KillDisconnected option for TigerVNC Xvnc sessions is now supported
   - Fixed an issue with delayed X KeyRelease events (bsc#1100453)
   - Force xrdp-sesman.service to start after xrdp.service. (bsc#1014524)
