FreeBSD : sudo -- Potential bypass of tty_tickets constraints (82cfd919-8213-11e2-9273-902b343deec9)

medium Nessus Plugin ID 64988
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Todd Miller reports :

A (potentially malicious) program run by a user with sudo access may be able to bypass the 'tty_ticket' constraints. In order for this to succeed there must exist on the machine a terminal device that the user has previously authenticated themselves on via sudo within the last time stamp timeout (5 minutes by default).

Solution

Update the affected package.
