CVE-2017-14178
In snapd 2.27 through 2.29.2 the 'snap logs' command could be made to call journalctl without match arguments and therefore allow unprivileged, unauthenticated users to bypass systemd-journald's access restrictions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
