+    <package name="dev-libs/libxml2" auto="yes" arch="*">

+  <background>
+    <p>libxml2 is the XML C parser and toolkit developed for the Gnome project.</p>
+  </background>
+  <description>
+    <p>The "xmlStringLenDecodeEntities()" function in parser.c contains a
+      boundary error which could possibly cause a heap-based buffer overflow.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>A remote attacker could entice a user to open a specially crafted XML
+      file in an application linked against libxml2, possibly resulting in the
+      remote execution of arbitrary code with the permissions of the user
+      running the application, or Denial of Service.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All libxml2 users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=dev-libs/libxml2-2.7.8-r4"
+    </code>
+    
+    <p>Packages which depend on this library may need to be recompiled. Tools
+      such as revdep-rebuild may assist in identifying some of these packages.
