+    poppassd_pam is a PAM-enabled server for changing system passwords
+    that can be used to change POP server passwords.
+    </p>
+  </background>
+  <description>
+    <p>
+    Gentoo Linux developer Marcus Hanwell discovered that poppassd_pam
+    did not check that the old password was valid before changing
+    passwords. Our investigation revealed that poppassd_pam did not call
+    pam_authenticate before calling pam_chauthtok.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote attacker could change the system password of any user,
+    including root. This leads to a complete compromise of the POP
+    accounts, and may also lead to a complete root compromise of the
+    affected server, if it also provides shell access authenticated using
+    system passwords.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All poppassd_pam users should migrate to the new package called
+    poppassd_ceti:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=net-mail/poppassd_ceti-1.8.4"</code>
+    <p>
+    Note: Portage will automatically replace the poppassd_pam
+    package by the poppassd_ceti package.
+    </p>
