Package : xrdp
Version : 0.5.0-2+deb7u1
CVE ID : CVE-2017-6967
Debian Bug : 858143

It was discovered that xrdp, a Remote Desktop Protocol (RDP) server,
calls the PAM function auth_start_session() in an incorrect location,
leading 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.

For Debian 7 "Wheezy", these problems have been fixed in version
0.5.0-2+deb7u1.

We recommend that you upgrade your xrdp packages.
