Description:
  During a source code audit, Chris Evans discovered several problems in
  the Portable Network Graphics (PNG) library libpng [1], some of which
  are security relevant. This OpenPKG update fixes all known issues.

  A stack-based buffer overflow in libpng which can be triggered to run
  arbitrary code by a malicious png file. The Common Vulnerabilities
  and Exposures (CVE) project assigned the id CAN-2004-0597 [2] to the
  problem.

  A NULL-pointer crash in libpng which can be triggered by a malicious
  png file. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2004-0598 [3] to the problem.

  Various possible integer overflows in libpng which may have security
  consequences. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2004-0599 [4] to the problem.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  rpm -q png". If you have the "png" package installed and its version
  is affected (see above), we recommend that you immediately upgrade it
  (see Solution) and its dependent packages (see above), if any, too
  [5][6].

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [7][8], fetch it from the OpenPKG FTP service [9][10] or a mirror
  location, verify its integrity [11], build a corresponding binary
  RPM from it [5] and update your OpenPKG installation by applying the
  binary RPM [6]. 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 png-1.2.5-2.1.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig png-1.2.5-2.1.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild png-1.2.5-2.1.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/png-1.2.5-2.1.1.*.rpm

  Additionally, we recommend that you rebuild and reinstall
  all dependent packages (see above), if any, too [5][6].
