Notes
Title of the patch: Security update for xrdp
Description of the patch: 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)
