Dependent Packages:  none

Description:
  Eric Romang has discovered [1] that GNU shtool [0] insecurely creates
  temporary files with predictable filenames, potentially allowing a
  local user to overwrite arbitrary files with a "symlink" attack. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2005-1751 [2] to the problem. On closer inspection, the Gentoo
  Security team discovered that the GNU shtool temporary file, once
  created, was being reused insecurely, too. The Common Vulnerabilities
  and Exposures (CVE) project assigned the id CAN-2005-1759 [3] to the
  problem.

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

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [6], fetch it from the OpenPKG FTP service [7] or a mirror location,
  verify its integrity [8], build a corresponding binary RPM from it [3]
  and update your OpenPKG installation by applying the binary RPM [5].
  For the affected release OpenPKG 2.3, perform the following operations
  to permanently fix the security problem (for other releases adjust
  accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.3/UPD
  ftp> get shtool-2.0.2-2.3.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig shtool-2.0.1-2.3.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild shtool-2.0.1-2.3.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/shtool-2.0.1-2.3.1.*.rpm

  Additionally, we recommend that you rebuild and reinstall
  all dependent packages (see above), if any, too [4][5].
