This new release of the eGenix.com pyOpenSSL Distribution includes the
following updates:

New in OpenSSL

 * Switched the included OpenSSL libraries to 1.0.2h.

   The OpenSSL 1.0.2 branch will receive long term support (LTS), so
   is an ideal basis for development. See
   https://openssl.org/news/secadv/20160503.txt ​for a complete
   list of security fixes in 1.0.2h. The following fixes are relevant
   for pyOpenSSL applications:

   - CVE-2016-2108 Two bugs in the ASN.1 parser were found which could
     cause memory corruption issues.

   - CVE-2016-2107 A MITM attacker can use a padding oracle attack to
     decrypt traffic when the connection uses an AES CBC cipher and
     the server support AES-NI. This issue was introduced as part of
     the fix for Lucky 13 padding attack (CVE-2013-0169).

    - Several low priority issues were fixed as well.

 * Updated the Mozilla CA root bundle to version 2016-04-16.

Please see the product changelog for the full set of changes.
