Description:
  In a previous OpenPKG security advisory [0], a buffer overflow
  vulnerability was addressed in the Portable Network Graphics (PNG)
  library libpng [1] in connection with 16-bit samples. The starting
  offsets for the loops are calculated incorrectly which may cause
  a buffer overrun beyond the beginning of the row buffer. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2002-1363 [2] to the problem. During an audit of Red Hat Linux
  updates, the Fedora Legacy team found another occurrence of this
  buffer overflow related to grayscale images. This OpenPKG update
  addresses the additional problem.

  Please check whether you are affected by running "/bin/rpm
  -q png" (and similarly for the other affected packages which have
  PNG included). If you have the "png" package (or one of the others)
  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 [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 2.0, perform the
  following operations to permanently fix the security problem (for
  other releases adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.0/UPD
  ftp> get png-1.2.5-2.0.2.src.rpm
  ftp> bye
  $ /bin/openpkg rpm -v --checksig png-1.2.5-2.0.2.src.rpm
  $ /bin/openpkg rpm --rebuild png-1.2.5-2.0.2.src.rpm
  $ su -
  # /bin/openpkg rpm -Fvh /RPM/PKG/png-1.2.5-2.0.2.*.rpm

  Additionally, we recommend that you rebuild and reinstall
  all dependent packages (see above), if any, too [3][4].
