  <background>
    <p>
    nss_ldap is a Name Service Switch module which allows 'passwd', 'group'
    and 'host' database information to be pulled from LDAP.
    </p>

  <description>
    <p>
    Josh Burley reported that nss_ldap does not properly handle the LDAP
    connections due to a race condition that can be triggered by
    multi-threaded applications using nss_ldap, which might lead to
    requested data being returned to a wrong process.
    </p>
  </description>
  <impact type="low">
    <p>
    Remote attackers could exploit this race condition by sending queries
    to a vulnerable server using nss_ldap, possibly leading to theft of
    user credentials or information disclosure (e.g. Dovecot returning
    wrong mailbox contents).
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All nss_ldap users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-auth/nss_ldap-258"</code>
  </resolution>
