+  <description>
+    <p>It was discovered that Gentoo’s default MUNGE installation suffered
+      from a privilege escalation vulnerability (munge user to root) due to
+      improper permissions and a runscript which called chown() on a user
+      controlled file.
+    </p>
+  </description>
+  <impact type="high">
+    <p>A local attacker, who either is already MUNGE’s system user or belongs
+      to MUNGE’s group, could potentially escalate privileges.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All MUNGE users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=sys-auth/munge-0.5.10-r2"
