CVE	CVSS	Summary
CVE-2016-2183	7.5 ( CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N )	The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
