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).

<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 &quot;&gt;=xfce-base/xfce4-panel-4.4.2&quot;</code>
