CVE-2017-1000082
systemd v233 and earlier fails to safely parse usernames starting with a numeric digit (e.g. "0day"), running the service in question with root privileges rather than the user intended.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.88%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
