OpenVPN versions before 2.3.15 and before 2.4.2 are vulnerable to reachable assertion when packet-ID counter rolls over resulting into Denial of Service of server by authenticated attacker. OpenVPN versiones anteriores a 2.3.15 y anteriores a 2.4.2, son vulnerables a una aserción alcanzable cuando el contador del identificador de paquete se devuelve como resultado de una denegación de servicio del servidor por parte de un atacante autenticado. • http://www.debian.org/security/2017/dsa-3900 http://www.securityfocus.com/bid/98443 http://www.securitytracker.com/id/1038473 https://community.openvpn.net/openvpn/wiki/QuarkslabAndCryptographyEngineerAudits • CWE-617: Reachable Assertion •

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 •

OpenVPN 2.x before 2.0.11, 2.1.x, 2.2.x before 2.2.3, and 2.3.x before 2.3.6 allows remote authenticated users to cause a denial of service (server crash) via a small control channel packet. OpenVPN 2.x anterior a 2.0.11, 2.1.x, 2.2.x anterior a 2.2.3, y 2.3.x anterior a 2.3.6 permite a usuarios remotos autenticados causar una denegación de servicio (caída del servidor) a través de un paquete de canal de control pequeño. • http://advisories.mageia.org/MGASA-2014-0512.html http://lists.opensuse.org/opensuse-security-announce/2014-12/msg00008.html http://www.debian.org/security/2014/dsa-3084 http://www.mandriva.com/security/advisories?name=MDVSA-2015:139 http://www.ubuntu.com/usn/USN-2430-1 https://community.openvpn.net/openvpn/wiki/SecurityAnnouncement-97597e732b • CWE-399: Resource Management Errors •

The openvpn_decrypt function in crypto.c in OpenVPN 2.3.0 and earlier, when running in UDP mode, allows remote attackers to obtain sensitive information via a timing attack involving an HMAC comparison function that does not run in constant time and a padding oracle attack on the CBC mode cipher. La función openvpn_decrypt en el archivo crypto.c en OpenVPN versiones 2.3.0 y anteriores, cuando se ejecuta en modo UDP, permite a los atacantes remotos obtener información confidencial por medio de un ataque de sincronización que implica una función de comparación HMAC que no se ejecuta en tiempo constante y un ataque de tipo padding oracle en el cifrado en modo CBC. • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/105568.html http://lists.fedoraproject.org/pipermail/package-announce/2013-May/105609.html http://lists.opensuse.org/opensuse-updates/2013-11/msg00012.html http://lists.opensuse.org/opensuse-updates/2013-11/msg00016.html http://www.mandriva.com/security/advisories?name=MDVSA-2013:167 http://www.openwall.com/lists/oss-security/2013/05/06/6 https://bugs.gentoo.org/show_bug.cgi?id=468756 https://bugzilla.redhat.com/show_ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

OpenVPN 2.0.7 and earlier, when configured to use the --management option with an IP that is not 127.0.0.1, uses a cleartext password for TCP sessions to the management interface, which might allow remote attackers to view sensitive information or cause a denial of service. • http://openvpn.net/man.html http://www.osvdb.org/25660 http://www.securityfocus.com/archive/1/432863/100/0/threaded http://www.securityfocus.com/archive/1/432867/100/0/threaded http://www.securityfocus.com/archive/1/433000/100/0/threaded •
