Description Cedric Buissart 🐶 2016-06-21 15:22:30 UTC
tmpfiles.d/systemd.conf in systemd v213 uses weak permissions for journal files under /run/log/journal/%m and /var/log/journal/%m, which allows local users to obtain sensitive information by reading these files.

Current RHEL version is shipped with v219, and is not affected by this issue.
