</p>
|
|
<ul>
|
|
<li>Evan
|
|
Broder and Anders Kaseorg of Ksplice, Inc. reported that the sudo
|
|
'secure path' feature does not properly handle multiple PATH variables
|
|
(CVE-2010-1646).</li>
|
|
<li>Markus Wuethrich of Swiss Post reported that
|
|
sudo fails to restrict access when using Runas groups and the group
|
|
(-g) command line option (CVE-2010-2956).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
A local attacker could exploit these vulnerabilities to gain the
|
|
ability to run certain commands with the privileges of other users,
|
|
including root, depending on the configuration.
|
|
</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-1.7.4_p3-r1"</code>
