FreeBSD : duo -- Two-factor authentication bypass (738e8ae1-46dd-11e7-a539-0050569f7e80)

High Nessus Plugin ID 100582


The remote FreeBSD host is missing a security-related update.


The duo security team reports :

An untrusted user may be able to set the http_proxy variable to an invalid address. If this happens, this will trigger the configured 'failmode' behavior, which defaults to safe. Safe mode causes the authentication to report a success.


Update the affected package.
