    <p>
    dhcpcd is a standards compliant DHCP client daemon. It requests an
    IP address and other information from the DHCP server, automatically
    configures the network interface, and tries to renew the lease time.
    </p>

  <description>
    <p>
    infamous42md discovered that dhcpcd can be tricked to read past
    the end of the supplied DHCP buffer. As a result, this might lead to a
    crash of the daemon.
    </p>
  </description>
  <impact type="normal">
    <p>
    With a malicious DHCP server an attacker could cause a Denial of
    Service by crashing the DHCP client.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All dhcpcd users should upgrade to the latest available version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/dhcpcd-1.3.22_p4-r11&quot;</code>
