Exposure of Sensitive Information to an Unauthorized Actor

CVE-2016-2183

High
7.5/10

Summary

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. openssl versions 0.9.x through 1.0.1t, 1.0.2 through 1.0.2h and 1.1.0-pre1 through 1.1.0-pre5 are vulnerable to this issue.
