    <p>
    PAM-MySQL is a PAM module used to authenticate users against a MySQL
    backend.
    </p>
  </background>
  <description>
    <p>
    A flaw in handling the result of pam_get_item() as well as further
    unspecified flaws were discovered in PAM-MySQL.
    </p>
  </description>
  <impact type="normal">
    <p>
    By exploiting the mentioned flaws an attacker can cause a Denial of
    Service and thus prevent users that authenticate against PAM-MySQL from
    logging into a machine. There is also a possible additional attack
    vector with more malicious impact that has not been confirmed yet.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PAM-MySQL users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=sys-auth/pam_mysql-0.7_rc1&quot;</code>
  </resolution>
