Affected Releases: Dependent Packages: none

Description:
  According to an e-matters Security Advisory [0] from Stefan Esser
  <s.esserematters.de>, a vulnerability exists in the Concurrent
  Versions System (CVS) [1] which allows remote compromise of CVS
  servers. The Common Vulnerabilities and Exposures (CVE) project
  assigned the id CAN-2003-0015 [2] to the problem.

  Please check whether you are affected by running "<prefix>/bin/rpm -q
  cvs". If you have the "cvs" 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 current release OpenPKG 1.1, perform the following
  operations to permanently fix the security problem (for other releases
  adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/1.1/UPD
  ftp> get cvs-1.11.2-1.1.1.src.rpm
  ftp> bye
  $ <prefix>/bin/rpm -v --checksig cvs-1.11.2-1.1.1.src.rpm
  $ <prefix>/bin/rpm --rebuild cvs-1.11.2-1.1.1.src.rpm
  $ su -
  # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/cvs-1.11.2-1.1.1.*.rpm

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