Description:
  According to security advisory CESA-2004-006 from Chris Evans, the
  libtiff [0] image en-/decoder suffers from several heap based buffer
  overflows. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2004-0803 [1] to the problem.

  Other code reviewers found integer overflows which affect memory
  allocation. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2004-0886 [2] to the problem.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  rpm -q tiff". If you have the "tiff" 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
  [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 tiff-3.6.1-2.1.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig tiff-3.6.1-2.1.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild tiff-3.6.1-2.1.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/tiff-3.6.1-2.1.1.*.rpm

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