        <p>The native R package installation mechanisms do not sufficiently validate installed source packages for path traversal.</p>
    </description>
    <impact type="normal">
        <p>Installation of a malicious R package could result in an arbitrary file overwrite which could result in arbitrary code execution, as might be seen with the overwrite of an authorized_keys file.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>

        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=dev-lang/R-4.0.4"
