Ubuntu 16.04 LTS : Systemd vulnerability (USN-3094-1)

high Nessus Plugin ID 93809

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Andrew Ayer discovered that Systemd improperly handled zero-length notification messages. A local unprivileged attacker could use this to cause a denial of service (init crash leading to system unavailability).

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.

Solution

Update the affected packages.
