                 (*) many packages are only affected if they (or their
                     underlying packages) used certain TLS/SSL related
                     options ("with_xxx") during build time. Above is
                     a worst case list. Packages known to only use
                     libcrypo without libssl are not affected and were
                     already omitted from the list.

Description:
  According to an OpenSSL [0] security advisory [1], a denial of service
  vulnerabilities exist in OpenSSL versions 0.9.6c to 0.9.6l inclusive
  and versions 0.9.7a to 0.9.7c inclusive.

  Testing performed by the OpenSSL group uncovered a null-pointer
  assignment in the do_change_cipher_spec() function. The Common
  Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2004-0079 [2] to the problem.

  Stephen Henson discovered a flaw in SSL/TLS handshaking code
  when using Kerberos ciphersuites. The OpenPKG packages make no
  use of this functionality but the patch was included anyway. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2004-0112 [3] to the problem.

  Please check whether you are affected by running "<prefix>/bin/rpm -q
  openssl". If you have the "openssl" package installed and its version
  is affected (see above), we recommend that you immediately upgrade it
  (see Solution) and it's dependent packages (see above), if any, too.
  [4][5]

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror
  location, verify its integrity [10], build a corresponding binary RPM
  from it [4] and update your OpenPKG installation by applying the
  binary RPM [5]. 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 openssl-0.9.7c-2.0.1.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig openssl-0.9.7c-2.0.1.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild openssl-0.9.7c-2.0.1.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/openssl-0.9.7c-2.0.1.*.rpm

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