<background>
<p>
sudo allows a system administrator to give users the ability to run
commands as other users.
</p>
</background>
<description>
<p>
Harald Koenig discovered that sudo incorrectly handles group
specifications in Runas_Alias (and related) entries when a group is
specified in the list (using %group syntax, to allow a user to run
commands as any member of that group) and the user is already a member
of that group.
</p>
</description>
<impact type="high">
<p>
A local attacker could possibly run commands as an arbitrary system
user (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-1.7.0"</code>
</resolution>
