+  <background>
+    <p>libvirt is a C toolkit for manipulating virtual machines.</p>

+  <description>
+    <p>Normally, only privileged users can coerce libvirt into creating or
+      opening existing files using the virStorageVol APIs; and such users
+      already have full privilege to create any domain XML.
+    </p>
+    
+    <p>But in the case of fine-grained ACLs, it is feasible that a user can be
+      granted storage_vol:create but not domain:write, and it violates
+      assumptions if such a user can abuse libvirt to access files outside of
+      the storage pool.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>When fine-grained Access Control Lists (ACL) are in effect, an
+      authenticated local user with storage_vol:create permission but without
+      domain:write permission maybe able to create or access arbitrary files
+      outside of the storage pool.
+    </p>
+  </impact>
+  <workaround>
+    <p>Don’t make use of fine-grained Access Control Lists (ACL) in libvirt;
+      In Gentoo, libvirt’s ACL support is disable by default unless you
+      enable the “policykit” USE flag.
+    </p>
+  </workaround>
+  <resolution>
+    <p>All libvirt users should upgrade to the latest version:</p>
