* Updated included OpenSSL libraries from OpenSSL 1.0.1r to
1.0.1s. See https://www.openssl.org/news/secadv/20160301.txt for a
complete list of changes. The following fixes are relevant for
- CVE-2016-0800 (DROWN attack) A cross-protocol attack was
discovered that could lead to decryption of TLS sessions by using
a server supporting SSLv2 and EXPORT cipher suites as a
Bleichenbacher RSA padding oracle.
As additional result of this attack, the default OpenSSL
configuration no longer includes the SSLv2 protocol support
starting with 1.0.1s.
- Several low priority issues related to memory leaks.
* Disabled SSLv2 support in all our OpenSSL library builds (no-ssl2).
* Disabled TLS compression in all our OpenSSL library builds
(no-comp). This may lead to problems with other libraries that
still expect to find these APIs. pyOpenSSL itself does not use
* Updated the Mozilla CA root bundle to version 2016-03-01. Nothing
much changed, except the date of the bundle file.
Please see the product changelog for the full set of changes.
