CVE-2017-11171 (opens in a new tab)How to fix?
There is no fixed version for Centos:6 gnome-session.
NVD Description
Note: Versions mentioned in the description apply only to the upstream gnome-session package and not the gnome-session package as distributed by Centos.
See How to fix? for Centos:6 relevant fixed versions and status.
Bad reference counting in the context of accept_ice_connection() in gsm-xsmp-server.c in old versions of gnome-session up until version 2.29.92 allows a local attacker to establish ICE connections to gnome-session with invalid authentication data (an invalid magic cookie). Each failed authentication attempt will leak a file descriptor in gnome-session. When the maximum number of file descriptors is exhausted in the gnome-session process, it will enter an infinite loop trying to communicate without success, consuming 100% of the CPU. The graphical session associated with the gnome-session process will stop working correctly, because communication with gnome-session is no longer possible.
