    Description:
      Triggered by a Debian bug report [1], a denial of service vulnerability
      was found in the ZLib compression library [0] versions 1.2.x
      (older versions are not affected). The problem arises from incorrect
      error handling in the inflate() and inflateBack() functions. The
      Common Vulnerabilities and Exposures (CVE) project assigned the id
      CAN-2004-0797 [2] to the problem.

      Please check whether you are affected by running "<prefix>/bin/openpkg
      rpm -q zlib". If you have the "zlib" package installed and its version
      is affected (see above), we recommend that you immediately upgrade it
      (see Solution) and its dependent packages (see above) as well [3][4].

    Solution:
      Select the updated source RPM appropriate for your OpenPKG release
      [5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
      location, verify its integrity [9], build a corresponding binary RPM
      from it [3] and update your OpenPKG installation by applying the
      binary RPM [4]. For the most recent release OpenPKG 2.1, perform the
      following operations to permanently fix the security problem (for
      other releases adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/2.1/UPD
      ftp> get zlib-1.2.1-2.1.1.src.rpm
      ftp> bye
      $ <prefix>/bin/openpkg rpm -v --checksig zlib-1.2.1-2.1.1.src.rpm
      $ <prefix>/bin/openpkg rpm --rebuild zlib-1.2.1-2.1.1.src.rpm
      $ su -
      # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/zlib-1.2.1-2.1.1.*.rpm

      Additionally, rebuild and reinstall any other dependent packages (see
      above) already installed in your OpenPKG instance. Only updating the
      "zlib" package is NOT sufficient because of the statically linked old
      "libz.a" code residing in the executables of other dependent packages.

      Due to transitive dependencies and because "zlib" is used by such many
      other libraries and programs, the convenient way to upgrade "zlib" and
      all affected packages is to use the "openpkg-tools" package:

      $ su -
      # <prefix>/bin/openpkg build -Ua | sh
