    <affected>
        <package name="app-admin/sudo" auto="yes" arch="*">
            <unaffected range="ge">1.9.12-r1</unaffected>

    <background>
        <p>sudo allows a system administrator to give users the ability to run commands as other users.</p>
    </background>
    <description>
        <p>In certain password input handling, sudo incorrectly assumes the password input is at least nine bytes in size, leading to a heap buffer overread.</p>
    </description>
    <impact type="normal">
        <p>In the worst case, the heap buffer overread can result in the denial of service of the sudo process.</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-r1"
        </code>
