<p>sudo (su “do”) allows a system administrator to delegate authority
|
|
to give certain users (or groups of users) the ability to run some (or
|
|
all) commands as root or another user while providing an audit trail of
|
|
the commands and their arguments.

<description>
|
|
<p>The fix present in app-admin/sudo-1.8.20_p1 (GLSA 201705-15) was
|
|
incomplete as it did not address the problem of a command with a newline
|
|
in the name.

<impact type="high">
|
|
<p>A local attacker could execute arbitrary code with root privileges.</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-1.8.20_p2"
|
|
</code>
