"Security Fix(es) :
- A flaw was found in the way the DES/3DES cipher was used
as part of the TLS/SSL protocol. A man-in-the-middle
attacker could use this flaw to recover some plaintext
data by capturing large amounts of encrypted traffic
between TLS/SSL server and client if the communication
used a DES/3DES based ciphersuite. (CVE-2016-2183)
Note: This update modifies the Python ssl module to disable 3DES
cipher suites by default."
