are affected by a vulnerability as referenced in the USN-6945-1 advisory.

    Rory McNamara discovered that wpa_supplicant could be made to load

    arbitrary shared objects by unprivileged users that have access to the control interface. An attacker
    could use this to escalate privileges to root.

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.");
