Summary
The scp_v0s_accept function in sesman/libscp/libscp_v0.c in the session manager in xrdp through 0.9.4 uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.

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

Summary
Security update for xrdp
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)
