<p>Two vulnerabilities have been discovered in sudo:</p>
|
|
|
|
<ul>
|
|
<li>When the sudoers file is configured with a Runas group, sudo does not
|
|
prompt for a password when changing to the new group (CVE-2011-0010).
|
|
</li>
|
|
<li>A format string vulnerability exists in the "sudo_debug()" function
|
|
(CVE-2012-0809).
|
|
</li>
|
|
</ul>

|
<impact type="high">
|
|
<p>A local attacker could possibly gain the ability to run arbitrary
|
|
commands with the privileges of other users or groups, including root.
|
|
</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-1.8.3_p2"
|
|
</code>
