Ubuntu 16.10 / 17.04 : systemd vulnerability (USN-3341-1)

Medium Nessus Plugin ID 101083


The remote Ubuntu host is missing a security-related patch.


An out-of-bounds write was discovered in systemd-resolved when handling specially crafted DNS responses. A remote attacker could potentially exploit this to cause a denial of service (daemon crash) or execute arbitrary code. (CVE-2017-9445).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected systemd package.
