+  <title>pam_ldap and nss_ldap: Plain text authentication leak</title>
+  <synopsis>
+    pam_ldap and nss_ldap fail to restart TLS when following a referral,
+    possibly leading to credentials being sent in plain text.

+    <p>
+    pam_ldap is a Pluggable Authentication Module which allows
+    authentication against an LDAP directory. nss_ldap is a Name Service
+    Switch module which allows 'passwd', 'group' and 'host' database
+    information to be pulled from LDAP. TLS is Transport Layer Security, a
+    protocol that allows encryption of network communications.
+    </p>

+  <description>
+    <p>
+    Rob Holland of the Gentoo Security Audit Team discovered that
+    pam_ldap and nss_ldap fail to use TLS for referred connections if they
+    are referred to a master after connecting to a slave, regardless of the
+    "ssl start_tls" ldap.conf setting.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker could sniff passwords or other sensitive information
+    as the communication is not encrypted.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    pam_ldap and nss_ldap can be set to force the use of SSL instead
+    of TLS.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All pam_ldap users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=sys-auth/pam_ldap-178-r1&quot;</code>
+    <p>
+    All nss_ldap users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose sys-auth/nss_ldap</code>
+  </resolution>
