+  <background>
+    <p>KAuth provides a convenient, system-integrated way to offload actions
+      that need to be performed as a privileged user (root, for example) to
+      small (hopefully secure) helper utilities.
+    </p>
+    
+    <p>The KDE libraries, basis of KDE and used by many open source projects.</p>
+  </background>
+  <description>
+    <p>KAuth and KDELibs contains a logic flaw in which the service invoking
+      D-Bus is not properly checked. This allows spoofing the identity of the
+      caller and with some carefully crafted calls can lead to gaining root
+      from an unprivileged account.
+    </p>
+  </description>
+  <impact type="high">
+    <p>A local attacker could spoof the identity of the caller invoking D-Bus,
+      possibly resulting in gaining privileges.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All KAuth users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=kde-frameworks/kauth-5.29.0-r1"
+    </code>
+    
+    <p>All KDELibs users should upgrade to the latest version:</p>
