The DHCP relay agent in Cisco Adaptive Security Appliance (ASA) and PIX 7.2 allows remote attackers to cause a denial of service (dropped packets) via a DHCPREQUEST or DHCPINFORM message that causes multiple DHCPACK messages to be sent from DHCP servers to the agent, which consumes the memory allocated for a local buffer. NOTE: this issue only occurs when multiple DHCP servers are used. El agente transmisor DHCP en Cisco Adaptive Security Appliance (ASA) y PIX 7.2 permite a atacantes remotos provocar una denegación de servicio (abandono de paquetes) mediante un mensaje DHCPREQUEST o DHCPINFORM que provoca que múltiples mensajes DHCPACK sean enviados desde servidores DHCP al agente, lo cual consume la memoria reservada para un búfer local. NOTA: esta situación sólo se da cuando se usan múltiples servidores DHCP. • http://secunia.com/advisories/25109 http://www.cisco.com/en/US/products/products_security_response09186a0080833172.html http://www.kb.cert.org/vuls/id/530057 http://www.osvdb.org/35330 http://www.securityfocus.com/bid/23763 http://www.securitytracker.com/id?1017999 http://www.securitytracker.com/id?1018000 http://www.vupen.com/english/advisories/2007/1635 https://exchange.xforce.ibmcloud.com/vulnerabilities/34026 •

Unspecified vulnerability in Cisco Adaptive Security Appliance (ASA) and PIX 7.1 before 7.1(2)49 and 7.2 before 7.2(2)17 allows remote attackers to cause a denial of service (device reload) via unknown vectors related to VPN connection termination and password expiry. Vulnerabilidad no especificada en Cisco Adaptive Security Appliance (ASA) y PIX 7.1 anterior a 7.1(2)49 y 7.2 anterior a 7.2(2)17 permite a atacantes remotos provocar denegación de servicio (recarga de dispositivo) a través de vectores desconocidos relacionados con el fin de la conexión VPN y el vencimiento de la contraseña. • http://secunia.com/advisories/25109 http://www.cisco.com/en/US/products/products_security_advisory09186a0080833166.shtml http://www.osvdb.org/35332 http://www.securityfocus.com/bid/23768 http://www.vupen.com/english/advisories/2007/1636 https://exchange.xforce.ibmcloud.com/vulnerabilities/34021 •

Race condition in Cisco Adaptive Security Appliance (ASA) and PIX 7.1 before 7.1(2)49 and 7.2 before 7.2(2)19, when using "clientless SSL VPNs," allows remote attackers to cause a denial of service (device reload) via "non-standard SSL sessions." Condición de carrera en el Cisco Adaptive Security Appliance (ASA) y en el PIX 7.1 anterior al 7.1(2)49 y el 7.2 anterior al 7.2(2)19, cuando se utiliza "VPNs SSL sin cliente", permite a atacantes remotos provocar una denegación de servicio (recargar el dispositivo) a través de "sesiones SSL no estándar". • http://secunia.com/advisories/25109 http://www.cisco.com/en/US/products/products_security_advisory09186a0080833166.shtml http://www.kb.cert.org/vuls/id/337508 http://www.osvdb.org/35333 http://www.securityfocus.com/bid/23768 http://www.vupen.com/english/advisories/2007/1636 https://exchange.xforce.ibmcloud.com/vulnerabilities/34023 •

Cisco PIX 6.3 and 7.0 allows remote attackers to cause a denial of service (blocked new connections) via spoofed TCP packets that cause the PIX to create embryonic connections that that would not produce a valid connection with the end system, including (1) SYN packets with invalid checksums, which do not result in a RST; or, from an external interface, (2) one byte of "meaningless data," or (3) a TTL that is one less than needed to reach the internal destination. • https://www.exploit-db.com/exploits/1338 https://www.exploit-db.com/exploits/26548 http://lists.grok.org.uk/pipermail/full-disclosure/2005-November/038971.html http://lists.grok.org.uk/pipermail/full-disclosure/2005-November/038983.html http://secunia.com/advisories/17670 http://securitytracker.com/id?1015256 http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_security_notice09186a0080624a37.html http://www.cisco.com/warp/public/707/cisco-response-20051122-pix.shtml http:/& •
