+  <synopsis>
+    Version 1.2.9 of ProFTPD introduced a vulnerability that causes CIDR-based
+    Access Control Lists (ACLs) to be treated as "AllowAll", thereby
+    allowing remote users full access to files available to the FTP daemon.

+    <p>
+    ProFTPD 1.2.9 introduced a vulnerability that allows CIDR-based ACLs (such
+    as 10.0.0.1/24) to be bypassed. The CIDR ACLs are disregarded, with the net
+    effect being similar to an "AllowAll" directive.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    This vulnerability may allow unauthorized files, including critical system
+    files to be downloaded and/or modified, thereby allowing a potential remote
+    compromise of the server.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    Users may work around the problem by avoiding use of CIDR-based ACLs.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    ProFTPD users are encouraged to upgrade to the latest version of the
+    package:
