CVE-2017-6967
Published: 17 March 2017
xrdp 0.9.1 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.
From the Ubuntu Security Team
It was discovered that PAM incorrectly initialized session modules. This could potentially bypass enforcement of limits.
