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.
