CVE-2016-2183

Original 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.

Affected software

• Python ≥ 3.4.0 < 3.4.7≥ 3.5.0 < 3.5.3≥ 2.7.0 < 2.7.13 Fixed in: 3.4.7, 3.5.3, 2.7.13 exact match
• OpenSSL = 1.0.1j= 1.0.1q= 1.0.2d= 1.0.2c= 1.0.2e= 1.0.1i exact match
