The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in Cisco IOS before 15.0(1)XA5 allows remote attackers to cause a denial of service (CPU consumption and device hang) by sending many Router Advertisement (RA) messages with different source addresses, as demonstrated by the flood_router6 program in the thc-ipv6 package, aka Bug ID CSCti33534. La implementación del protocolo Neighbor Discovery (ND) en la pila de IPv6 en Cisco IOS anterior a v15.0(1)XA5 permite a atacantes remotos provocar una denegación de servicio (consumo de CPU y bloqueo de dispositivo) mediante el envío de muchos mensajes Router Advertisement (AR) con distintas direcciones origen, como demostró el programa flood_router6 en el paquete thc-ipv6, también conocido como ID de error CSCti33534 • http://events.ccc.de/congress/2010/Fahrplan/events/3957.en.html http://mirror.fem-net.de/CCC/27C3/mp3-audio-only/27c3-3957-en-ipv6_insecurities.mp3 http://mirror.fem-net.de/CCC/27C3/mp4-h264-HQ/27c3-3957-en-ipv6_insecurities.mp4 http://www.ciscosystems.com/en/US/docs/ios/15_0/15_0x/15_01_XA/rn800xa.pdf http://www.securityfocus.com/bid/45760 http://www.youtube.com/watch?v=00yjWB6gGy8 https://exchange.xforce.ibmcloud.com/vulnerabilities/64589 • CWE-400: Uncontrolled Resource Consumption •

The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress. La implementación del protocolo TCP en (1) Linux, (2) plataformas basadas en BSD Unix, (3) Microsoft Windows, (4) productos Cisco, y probablemente otros sistemas operativos, permite a atacantes remotos provocar una denegación de servicio (agotamiento de cola de conexión) a través de múltiples vectores que manipulan información en la tabla de estados del TCP, como lo demuestra sockstress. • http://blog.robertlee.name/2008/10/conjecture-speculation.html http://insecure.org/stf/tcp-dos-attack-explained.html http://lists.immunitysec.com/pipermail/dailydave/2008-October/005360.html http://marc.info/?l=bugtraq&m=125856010926699&w=2 http://searchsecurity.techtarget.com.au/articles/27154-TCP-is-fundamentally-borked http://www.cisco.com/en/US/products/products_security_advisory09186a0080af511d.shtml http://www.cisco.com/en/US/products/products_security_response09186a0080a15120.html http://www.cpni • CWE-16: Configuration •
