+  <title>Dnsmasq: Multiple vulnerabilities</title>
+  <synopsis>
+    Multiple vulnerabilities in Dnsmasq might result in the remote execution of
+    arbitrary code, or a Denial of Service.

+    <p>
+    Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP
+    server. It includes support for Trivial FTP (TFTP).
+    </p>
+  </background>
+  <description>
+    <p>
+    Multiple vulnerabilities have been reported in the TFTP functionality
+    included in Dnsmasq:
+    </p>
+    <ul>
+    <li>Pablo Jorge and Alberto Solino
+    discovered a heap-based buffer overflow (CVE-2009-2957).</li>
+    <li>An
+    anonymous researcher reported a NULL pointer reference
+    (CVE-2009-2958).</li>
+    </ul>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker in the local network could exploit these
+    vulnerabilities by sending specially crafted TFTP requests to a machine
+    running Dnsmasq, possibly resulting in the remote execution of
+    arbitrary code with the privileges of the user running the daemon, or a
+    Denial of Service. NOTE: The TFTP server is not enabled by default.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    You can disable the TFTP server either at buildtime by not enabling the
+    "tftp" USE flag, or at runtime. Make sure "--enable-tftp" is not set in
+    the DNSMASQ_OPTS variable in the /etc/conf.d/dnsmasq file and
+    "enable-tftp" is not set in /etc/dnsmasq.conf, either of which would
+    enable TFTP support if it is compiled in.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Dnsmasq users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=net-dns/dnsmasq-2.5.0"</code>
+  </resolution>
