It looks like there is an option to suppress this. I just encountered the same problem and found information in the following tickets to be helpful:
https://bugs.launchpad.net/ubuntu/+source/rkhunter/+bug/1453952 https://bugs.launchpad.net/ubuntu/+source/rkhunter/+bug/219840
I created a /etc/rkhunter.conf.local with the following content:
``` ALLOWHIDDENDIR=/dev/shm/byobu-*-????????/.last.tmux ALLOWDEVFILE=/dev/shm/byobu-*-????????/.last.tmux/* ALLOWDEVFILE=/dev/shm/byobu-*-????????/*/* ALLOWDEVFILE=/dev/shm/byobu-*-????????/* ALLOWDEVFILE=/dev/shm/sem.* ```
I don't think the is a bug, you are basically asking how to configure your whitelist. It would have been more constructive an useful to the community to post it as a question on AskUbuntu. I think.
