+  <description>
+    <p>
+    Mattias Bengtsson and Philip Olausson have discovered a buffer overflow
+    vulnerability in the function fcgi_env_add() in the file mod_fastcgi.c
+    when processing overly long HTTP headers.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could send a specially crafted request to the
+    vulnerable Lighttpd server, resulting in the remote execution of
+    arbitrary code with privileges of the user running the web server. Note
+    that mod_fastcgi is disabled in Gentoo's default configuration.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    Edit the file /etc/lighttpd/lighttpd.conf and comment the following
+    line: "include mod_fastcgi.conf"
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Lighttpd users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=www-servers/lighttpd-1.4.18&quot;</code>
