        <p>Multiple vulnerabilities have been discovered in cpio. Please review the CVE identifiers referenced below for details.</p>
    </description>
    <impact type="normal">
        <p>GNU cpio allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All cpio users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=app-arch/cpio-2.13-r1"
        </code>
