    Xfce is a GTK+ 2 based desktop environment that allows to run a modern
    desktop environment on modest hardware.

    <p>
    Gregory Andersen reported that the Xfce4 panel does not correctly
    calculate memory boundaries, leading to a stack-based buffer overflow
    in the launcher_update_panel_entry() function (CVE-2007-6531). Daichi
    Kawahata reported libxfcegui4 did not copy provided values when
    creating "SessionClient" structs, possibly leading to access of freed
    memory areas (CVE-2007-6532).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to install a specially crafted
    "rc" file to execute arbitrary code via long strings in the "Name" and
    "Comment" fields or via unspecified vectors involving the second
    vulnerability.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Xfce4 panel users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=xfce-base/xfce4-panel-4.4.2"</code>
    <p>
    All libxfcegui4 users should upgrade to the latest version:

    <code>
