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 •
