  <description>
    <p>
    Cyrus-SASL contains a remote buffer overflow in the digestmda5.c file.
    Additionally, under certain conditions it is possible for a local user
    to exploit a vulnerability in the way the SASL_PATH environment
    variable is honored (CAN-2004-0884).
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker might be able to execute arbitrary code with the Effective
    ID of the application calling the Cyrus-SASL libraries.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Cyrus-SASL users should upgrade to the latest stable version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv &quot;&gt;=dev-libs/cyrus-sasl-2.1.18-r2&quot;
    # emerge &quot;&gt;=dev-libs/cyrus-sasl-2.1.18-r2&quot;</code>
