CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the DES/3DES cipher, used as a part of the
SSL/TLS protocol. By capturing large amounts of encrypted traffic between the
SSL/TLS server and the client, a remote attacker able to conduct a
man-in-the-middle attack could exploit this vulnerability to recover the
plaintext data and obtain sensitive information. This vulnerability is known
as the SWEET32 Birthday attack.
