+  <title>scponly: Multiple privilege escalation issues</title>
+  <synopsis>
+    Local users can exploit an scponly flaw to gain root privileges, and
+    scponly restricted users can use another vulnerability to evade shell
+    restrictions.

+  <background>
+    <p>
+    scponly is a restricted shell, allowing only a few predefined commands.
+    It is often used as a complement to OpenSSH to provide access to remote
+    users without providing any remote execution privileges.
+    </p>
+  </background>
+  <description>
+    <p>
+    Max Vozeler discovered that the scponlyc command allows users to chroot
+    into arbitrary directories. Furthermore, Pekka Pessi reported that
+    scponly insufficiently validates command-line parameters to a scp or
+    rsync command.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A local attacker could gain root privileges by chrooting into arbitrary
+    directories containing hardlinks to setuid programs. A remote scponly
+    user could also send malicious parameters to a scp or rsync command
+    that would allow to escape the shell restrictions and execute arbitrary
+    programs.
+    </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 "&gt;=net-misc/scponly-4.2"</code>
