Cisco 4100 and 4400, Airespace 4000, and Catalyst 6500 and 3750 Wireless LAN Controller (WLC) software before 3.2 20070727, 4.0 before 20070727, and 4.1 before 4.1.180.0 allows remote attackers to cause a denial of service (traffic amplification or ARP storm) via a crafted unicast ARP request that (1) has a destination MAC address unknown to the Layer-2 infrastructure, aka CSCsj69233; or (2) occurs during Layer-3 roaming across IP subnets, aka CSCsj70841. Cisco 4100 y 4400, Airespace 4000, y Catalyst 6500 y 3750 Wireless LAN Controller (WLC) software anterior a 3.2 20070727, 4.0 anterior a 20070727, y 4.1 anterior a 4.1.180.0 permite a atacantes remotos provocar denegación de servicio (amplificación de tráfico o tormenta ARP)a través de una respuesta ARP unicast que (1) tiene una dirección de destino MAC desconocida a la infraestructura Layer-2, también conocida como CSCsj69233; o (2) ocurre a lo lago del roaming Layer-3 a través de subredes IP, también conocido como CSCsj70841. • http://secunia.com/advisories/26161 http://www.cisco.com/en/US/products/products_security_advisory09186a008088ab28.shtml http://www.securityfocus.com/bid/25043 http://www.securitytracker.com/id?1018444 http://www.vupen.com/english/advisories/2007/2636 https://exchange.xforce.ibmcloud.com/vulnerabilities/35576 •

Cisco 4100 and 4400, Airespace 4000, and Catalyst 6500 and 3750 Wireless LAN Controller (WLC) software 4.1 before 4.1.180.0 allows remote attackers to cause a denial of service (ARP storm) via a broadcast ARP packet that "targets the IP address of a known client context", aka CSCsj50374. Cisco 4100 y 4400, Airespace 4000, y Catalyst 6500 y 3750 Wireless LAN Controller (WLC) software 4.1 versiones anteriores a 4.1.180.0, permiten a atacantes remotos provocar una denegación de servicio (tormenta ARP) mediante un distribución a todos de paquete ARP que "coincide con la dirección IP de un contexto de cliente conocido", también conocido como CSCsj50374. • http://secunia.com/advisories/26161 http://www.cisco.com/en/US/products/products_security_advisory09186a008088ab28.shtml http://www.securityfocus.com/bid/25043 http://www.securitytracker.com/id?1018444 http://www.vupen.com/english/advisories/2007/2636 https://exchange.xforce.ibmcloud.com/vulnerabilities/35576 https://exchange.xforce.ibmcloud.com/vulnerabilities/44591 •
