+  <title>Netkit FTP Server: Privilege escalation</title>
+  <synopsis>
+    An incorrect seteuid() call could allow an FTP user to access some files or
+    directories that would normally be inaccessible.

+    <p>
+    Paul Szabo reported that an incorrect seteuid() call after the chdir()
+    function can allow an attacker to access a normally forbidden
+    directory, in some very particular circumstances, for example when the
+    NFS-hosted targetted directory is not reachable by the client-side root
+    user. Additionally, some potentially exploitable unchecked setuid()
+    calls were also fixed.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A local attacker might craft his home directory to gain access through
+    ftpd to normally forbidden directories like /root, possibly with
+    writing permissions if seteuid() fails and if the ftpd configuration
+    allows that. The unchecked setuid() calls could also lead to a root FTP
+    login, depending on the FTP server configuration.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Netkit FTP Server users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=net-ftp/netkit-ftpd-0.17-r4&quot;</code>
