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
