    Description:
      A setuid and setgid application vulnerability was found in the Cyrus
      SASL library [0]. At application startup, libsasl2 attempts to build a
      list of all available SASL plugins which are available on the system.
      To do so, the library searches for and attempts to load every shared
      library found within the plugin directory. This location can be set
      with the SASL_PATH environment variable.

      In situations where an untrusted local user can affect the environment
      of a privileged process, this behavior could be exploited to run
      arbitrary code with the privileges of a setuid or setgid application.
      The Common Vulnerabilities and Exposures (CVE) project assigned the
      identifier CAN-2004-0884 [1] to the problem.

      Please check whether you are affected by running "<prefix>/bin/openpkg
      rpm -q sasl". If you have the "sasl" package installed and its version
      is affected (see above), we recommend that you immediately upgrade it
      (see Solution) and any dependent packages as well [2][3].

    Solution:
      Select the updated source RPM appropriate for your OpenPKG release
      [4][5], fetch it from the OpenPKG FTP service [6][7] or a mirror
      location, verify its integrity [8], build a corresponding binary RPM
      from it [2] and update your OpenPKG installation by applying the
      binary RPM [3]. For the most recent release OpenPKG 2.2, perform the
      following operations to permanently fix the security problem (for
      other releases adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/2.2/UPD
      ftp> get sasl-2.1.19-2.2.1.src.rpm
      ftp> bye
      $ <prefix>/bin/openpkg rpm -v --checksig sasl-2.1.19-2.2.1.src.rpm
      $ <prefix>/bin/openpkg rpm --rebuild sasl-2.1.19-2.2.1.src.rpm
      $ su -
      # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/sasl-2.1.19-2.2.1.*.rpm

      Additionally, we recommend that you rebuild and reinstall
      any dependent packages (see above) as well [2][3].
