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

high Nessus Plugin ID 93809

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3094-1 advisory.

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).

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
