  <background>
    <p>
    mod_auth_pgsql is an Apache2 module that allows user authentication
    against a PostgreSQL database.
    </p>
  </background>
  <description>
    <p>
    The error logging functions of mod_auth_pgsql fail to validate certain
    strings before passing them to syslog, resulting in format string
    vulnerabilities.
    </p>
  </description>
  <impact type="high">
    <p>
    An unauthenticated remote attacker could exploit these vulnerabilities
    to execute arbitrary code with the rights of the user running the
    Apache2 server by sending specially crafted login names.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All mod_auth_pgsql users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apache/mod_auth_pgsql-2.0.3&quot;</code>
  </resolution>
