+  <title>rssh, scponly: Unrestricted command execution</title>
+  <synopsis>
+    rssh and scponly do not filter command-line options that can be exploited
+    to execute any command, thereby allowing a remote user to completely bypass
+    the restricted shell.

+    <p>
+    rssh and scponly are two restricted shells, allowing only a few
+    predefined commands. They are often used as a complement to OpenSSH to
+    provide access to remote users without providing any remote execution
+    privileges.

+    <p>
+    Jason Wies discovered that when receiving an authorized command from an
+    authorized user, rssh and scponly do not filter command-line options
+    that can be used to execute any command on the target host.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    Using a malicious command, it is possible for a remote authenticated
+    user to execute any command (or upload and execute any file) on the
+    target machine with user rights, effectively bypassing any restriction
+    of scponly or rssh.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All scponly users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/scponly-4.0&quot;</code>
+    <p>
+    All rssh users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-shells/rssh/rssh-2.2.3&quot;</code>
