Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.
