https://notcve.org/view.php?id=CVE-2016-6329
OpenVPN, when using a 64-bit block cipher, makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTP-over-OpenVPN session using Blowfish in CBC mode, aka a "Sweet32" attack. OpenVPN, cuando utiliza un cifrado de bloques de 64 bits, facilita a atacantes remotos obtener datos de texto plano a través de un ataque birthday contra una sesión encriptada de larga duración, como lo demuestra una sesión HTTP-over-OpenVPN usando Blowfish en modo CBC, también conocido como ataque "Sweet32". • http://www-01.ibm.com/support/docview.wss?uid=nas8N1021697 http://www-01.ibm.com/support/docview.wss?uid=swg21991482 http://www-01.ibm.com/support/docview.wss?uid=swg21995039 http://www.securityfocus.com/bid/92631 http://www.securitytracker.com/id/1036695 https://cert-portal.siemens.com/productcert/pdf/ssa-556833.pdf https://community.openvpn.net/openvpn/wiki/SWEET32 https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05369403 https://security.gentoo&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues •
