Description

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.(CVE-2016-2183)

Important : This vulnerability is caused by functionality in the OpenSSL software library. A viable mitigation is available in the mitigation section. There will be no further updates to this article, unless new information is discovered.

Impact

Remote attackers may be able to obtain cleartext data using a birthday attack againstlong-duration encrypted sessions.
