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:
OpenSSL is an open-source implementation of the SSL/TLS protocol.
This new release of the eGenix.com pyOpenSSL Distribution
includes the following updates:
- CVE-2015-3194 The signature verification routines will crash with a NULL pointer dereference, if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. This can be exploited in as DoS attack in applications which performs certificate verification.
- CVE-2015-3195: When presented with a malformed X509_ATTRIBUTE structure OpenSSL will leak memory.
- CVE-2015-3196: If PSK identity hints are received by a multi-threaded client, then the values are wrongly updated in the parent SSL_CTX structure. This can potentially lead to a double free of the identify hint data, leading to a segfault.
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
pip install egenix-pyopenssl
will get you the package with OpenSSL libraries installed. Please see our installation instructions for details.
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.
Please visit the eGenix pyOpenSSL Distribution page for downloads, instructions on installation and documentation of the package.
Before installing this version of pyOpenSSL, please make sure that you uninstall any previously installed pyOpenSSL version. Otherwise, you could end up not using the included OpenSSL libs.
