sudo: Privilege escalation

Background

sudo allows a system administrator to give users the ability to run commands as other users. Access to commands may also be granted on a range to hosts.

Description

An error in sudo may allow unintended IPv4 hosts to be granted access to commands.

Impact

A local attacker could gain escalated privileges.

Workaround

There is no known workaround at this time.

Resolution

All sudo users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.5_p1"
