+  <impact type="normal">
+    <p>
+    By enticing a user to extract a specially crafted tar archive, a remote
+    attacker could extract files to arbitrary locations outside of the
+    specified directory with the permissions of the user running GNU Tar.

+    <p>
+    There is no known workaround at this time.

+  </workaround>

+    <p>
+    All GNU Tar users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/tar-1.18-r2&quot;</code>
