<p>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>
|
|
<p>Multiple vulnerabilities have been found in sudo:</p>
|
|
|
|
<ul>
|
|
<li>sudo does not correctly validate the controlling terminal on a system
|
|
without /proc or when the tty_tickets option is enabled.
|
|
</li>
|
|
<li>sudo does not properly handle the clock when it is set to the epoch.</li>
|
|
</ul>
|
|

|
<impact type="high">
|
|
<p>A local attacker with sudo privileges could connect to the stdin,
|
|
stdout, and stderr of the terminal of a user who has authenticated with
|
|
sudo, allowing the attacker to hijack the authorization of the other
|
|
user. Additionally, a local or physically proximate attacker could set
|
|
the system clock to the epoch, bypassing time restrictions on sudo
|
|
authentication.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All sudo users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.6_p7"
|
|
</code>
