                 (*) marked packages are only affected if certain build
                     options ("with_xxx") were used at build time. See
                     Appendix below for details.

Description:
  According to an OpenSSL [0] security advisory [1], multiple
  vulnerabilities exist in OpenSSL versions up to and including 0.9.6j
  and 0.9.7b:

  1. Certain ASN.1 encodings that are rejected as invalid by the ASN.1
     parser can trigger a bug in the deallocation of the corresponding
     data structure, corrupting the stack.

  2. Unusual ASN.1 tag values can cause an out of bounds read under
     certain circumstances.

  3. A malformed public key in a certificate will crash the verify code
     if it is set to ignore public key decoding errors (which is usually
     not the case, except for debugging purposes).

  4. Due to an error in the SSL/TLS protocol handling, a server will
     parse a client certificate when one is not specifically requested.
     This means that all OpenSSL based SSL/TLS servers can be attacked
     using vulnerabilities 1, 2 and 3 even if they don't enable client
     authentication.

  The Common Vulnerabilities and Exposures (CVE) project assigned the
  ids CAN-2003-0543 [2], CAN-2003-0544 [3] and CAN-2003-0545 [4] to the
  problems.

  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), too. [5][6]

Solution:
  Select the updated source RPM appropriate for your OpenPKG release
  [7][8], fetch it from the OpenPKG FTP service [9][10] or a mirror
  location, verify its integrity [11], build a corresponding binary
  RPM from it [5] and update your OpenPKG installation by applying the
  binary RPM [6]. For the current release OpenPKG 1.3, perform the
  following operations to permanently fix the security problem (for
  other releases adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/1.3/UPD
  ftp> get openssl-0.9.7b-1.3.2.src.rpm
  ftp> bye
  $ <prefix>/bin/rpm -v --checksig openssl-0.9.7b-1.3.2.src.rpm
  $ <prefix>/bin/rpm --rebuild openssl-0.9.7b-1.3.2.src.rpm
  $ su -
  # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/openssl-0.9.7b-1.3.2.*.rpm

  Additionally, we you have to rebuild and reinstall all dependent
  packages (see above), too. [5][6]
________________________________________________________________________

Appendix:
  Some packages are only affected if certain package options
  ("with_xxx") were used at build time. Please check whether you are
  affected by running "<prefix>/bin/rpm -qi <package>". The table below
  lists all those packages, their options and values that make up the
  difference regarding this advisory for OpenPKG CURRENT, 1.3 and 1.2.
  Packages or options that were not available in a particular release
  are marked "=".
