Synopsis:          Moderate: python security update
Advisory ID:       SLSA-2018:2123-1
Issue Date:        2018-07-03
CVE Numbers:       CVE-2016-2183
--

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.
