I am using Ubuntu 17.10 and have recently installed and run rkhunter 1.4.4. I got the following warnings about suspicious shared memory segments:
/usr/lib/nautilus-desktop PID 1867
Is this a problem? Could there be a problem with rkhunter not playing well with the newest Ubuntu? Can I safely ignore this, especially if I don't get a warning when I am not running Firefox at the same time, and I do get a warning if Firefox is running?
