Package:             openssl
Vulnerability:       potential SSL 2.0 rollback 
OpenPKG Specific:    no

Affected Releases:   Affected Packages:        Corrected Packages:
OpenPKG CURRENT      <= openssl-0.9.8-2005092  >= openssl-0.9.8a-20051011
OpenPKG 2.4          <= openssl-0.9.7g-2.4.1   >= openssl-0.9.7g-2.4.2
OpenPKG 2.3          <= openssl-0.9.7e-2.3.2   >= openssl-0.9.7e-2.3.3

Dependent Packages:  unknown

Description:
  According to a vendor security advisory [0], a potential SSL 2.0
  protocol rollback attack vulnerability exists in the cryptography
  toolkit OpenSSL [1]. The vulnerability potentially affects
  applications that use the SSL/TLS server implementation provided
  by OpenSSL. Such applications are affected if they use the option
  "SSL_OP_MSIE_SSLV2_RSA_PADDING". Applications using neither
  "SSL_OP_MSIE_SSLV2_RSA_PADDING" nor "SSL_OP_ALL" are not affected.
  Also, applications that disable use of SSL 2.0 are not affected. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2005-2969 [2] to the problem.

  Please check whether you are affected by running "<prefix>/bin/openpkg
  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) [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 2.4, perform the
  following operations to permanently fix the security problem (for
  other releases adjust accordingly).

  $ ftp ftp.openpkg.org
  ftp> bin
  ftp> cd release/2.4/UPD
  ftp> get openssl-0.9.7g-2.4.2.src.rpm
  ftp> bye
  $ <prefix>/bin/openpkg rpm -v --checksig openssl-0.9.7g-2.4.2.src.rpm
  $ <prefix>/bin/openpkg rpm --rebuild openssl-0.9.7g-2.4.2.src.rpm
  $ su -
  # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/openssl-0.9.7g-2.4.2.*.rpm
