       An update that solves three vulnerabilities and has 5 fixes
       is now available.
    
    Description:
    
       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).
    
       These non-security issues were fixed:
    
       - 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)
       - Fixed a regression connecting from Windows 10. (bsc#1090174)
