Canonical informs Ubuntu users that it updated the systemd packages in the Ubuntu 16.10 (Yakkety Yak) and Ubuntu 17.04 (Zesty Zapus) operating systems to patch a recently discovered security issue.

The new systemd vulnerability (CVE-2017-9445) appears to affect the systemd-resolved component, which could allow a remote attacker to crash the systemd daemon by causing a denial of service or run malicious programs on the vulnerable, unpatched machines by using a specially crafted DNS response.
