    <affected>
        <package name="app-admin/sudo" auto="yes" arch="*">
            <unaffected range="ge">1.9.12_p2</unaffected>

    <background>
        <p>sudo allows a system administrator to give users the ability to run commands as other users.</p>
    </background>
    <description>
        <p>The sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process.</p>
    </description>
    <impact type="high">
        <p>The improper processing of user&#39;s environment variables could lead to the editing of arbitrary files as root, potentially leading to root privilege escalation.</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-1.9.12_p2"
        </code>
