Severity: high
Exploitable: local
Date: 2017-10-08
Bug(s): #620482
ID: 201710-04

Synopsis

A vulnerability in sudo allows local users to gain root privileges.

Background

sudo (su “do”) allows a system administrator to delegate authority
to give certain users (or groups of users) the ability to run some (or

the commands and their arguments.


Affected Packages

Package: app-admin/sudo
Vulnerable: < 1.8.20_p2
Unaffected: >= 1.8.20_p2

Impact

Workaround

There is no known workaround at this time.

Resolution

All sudo users should upgrade to the latest version:
