The eGenix.com pyOpenSSL Distribution includes everything you need to
get started with SSL in Python. It comes with an easy to use installer
that includes the most recent OpenSSL library versions in pre-compiled
form, making your application independent of OS provided OpenSSL libraries:
Fixed a bug in the build process which resulted in the CA bundle files not get installed in the OpenSSL/ package dir.
Added a work-around for recent pip versions not showing the installer
output, causing an apparently hanging installation process. The
installer will now use a timeout when entering the crypto confirmation
and report how to fix the problem (by using an environment variable
EGENIX_CRYPTO_CONFIRM for confirmation).
Updated the Mozilla CA root bundle to version 2015-04-22.
Various minor fixes to the web installer to make
installations on Linux and FreeBSD more robust, having pip uninstall not
remove the .pyc/.pyo files, intermittent error causing a source
installation in some rare cases.
Logjam attack: OpenSSL 1.0.1n includes DHE man-in-the-middle downgrade protection.
CVE-2015-1788: Possible infinite loop during client authentication, which can be used for Denial of Service (DoS) attacks.
CVE-2015-1789: X509_cmp_time does not properly check the length of the ASN1_TIME
string and can read a few bytes out of bounds, which can lead to a segmentation fault.
CVE-2015-1790: The PKCS#7 parsing code does not handle missing inner EncryptedContent
correctly, which can lead to a NULL pointer dereference on parsing.
CVE-2015-1792:When verifying a signedData message the CMS code can enter an infinite loop
if presented with an unknown hash function OID.
CVE-2015-1791:If a NewSessionTicket is received by a multi-threaded client when attempting to
reuse a previous ticket then a race condition can occur potentially leading to
a double free of the ticket data.

pyOpenSSL / OpenSSL Binaries Included
In addition to providing sources, we make binaries available that include both pyOpenSSL and the necessary OpenSSL libraries for all supported platforms: Windows, Linux, Mac OS X and FreeBSD, for x86 and x64.
To simplify installation, we have uploaded a web installer to PyPI which will automatically choose the right binary for your platform, so a simple
We have also added .egg-file distribution versions of our eGenix.com pyOpenSSL Distribution for Windows, Linux and Mac OS X to the available download options. These make setups using e.g. zc.buildout and other egg-file based installers a lot easier.
