Dependent Packages:  none

Description:
  According to a posting on Bugtraq [1], Shaun Colley discovered and
  researched a stack-based buffer overflow vulnerability which exists in
  the GNU Sharutils [2] due to lack of bounds checking when handling the
  '-o' command-line option.

  Please check whether you are affected by running "<prefix>/bin/rpm
  -q sharutils". If you have the "sharutils" 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
  [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 sharutils-4.2.1-2.0.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig sharutils-4.2.1-2.0.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild sharutils-4.2.1-2.0.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/sharutils-4.2.1-2.0.1.*.rpm
