FreeBSD : sudo -- Authentication bypass when clock is reset (764344fb-8214-11e2-9273-902b343deec9)

medium Nessus Plugin ID 64987
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 :

The flaw may allow someone with physical access to a machine that is not password-protected to run sudo commands without knowing the logged in user's password. On systems where sudo is the principal way of running commands as root, such as on Ubuntu and Mac OS X, there is a greater chance that the logged in user has run sudo before and thus that an attack would succeed.

Solution

Update the affected package.
