Vulnerabilidades

Desbordamiento de búfer basado en montículo en el servicio Juniper HTTP Service permite a atacantes remotos ejecutar código de su elección mediante un paquete HTTP manipulado. NOTA: a fecha de 16/10/2007, la única revelación es un vago preaviso sin información de uso inmediato. Sin embargo, dado que proviene de un…

Vulnerabilidad de secuencia de comando en sitios cruzados (XSS) en la interfaz de entrada de administración web en Juniper Networks (Redline) DX 5.1.x, permite a atacantes remotos inyectar secuencias de comandos web o HTML a través del campo de entrada username.

Fuga de memoria en Juniper JUNOS de 6.4 a 8.0, construidos antes del 10 de mayo de 2006, permite a atacantes remotos provocar una denegación de servicio (agotamiento del paquete de memoria del núcleo y caída) a través de paquetes IPv6 manipulados cuyos búfers no se liberan después de ser procesados.

Buffer overflow in JuniperSetupDLL.dll, loaded from JuniperSetup.ocx by the Juniper SSL-VPN Client when accessing a Juniper NetScreen IVE device running IVE OS before 4.2r8.1, 5.0 before 5.0r6.1, 5.1 before 5.1r8, 5.2 before 5.2r4.1, or 5.3 before 5.3r2.1, allows remote attackers to execute arbitrary code via a long…

Unspecified vulnerability in Juniper Networks JUNOSe E-series routers before 7-1-1 has unknown impact and remote attack vectors related to the DNS "client code," as demonstrated by the OUSPG PROTOS DNS test suite.

Juniper NetScreen-Security Manager (NSM) 2004 FP2 and FP3 allow remote attackers to cause a denial of service (crash or hang of server components that are automatically restarted) via a long crafted string on (1) port 7800 (the GUI Server port) or (2) port 7801 (the Device Server port).

The Internet Key Exchange version 1 (IKEv1) implementation in Juniper JUNOS and JUNOSe software for M, T, and J-series routers before release 6.4, and E-series routers before 7-1-0, allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IKE packets, as demonstrated by the…

Behavioral discrepancy information leak in Juniper Netscreen VPN running ScreenOS 5.2.0 and earlier, when using IKE with pre-shared key authentication, allows remote attackers to enumerate valid usernames via an IKE Aggressive Mode packet, which generates a response if the username is valid but does not respond when…

Juniper JUNOS 5.x through JUNOS 7.x allows remote attackers to cause a denial of service (routing disabled) via a large number of MPLS packets, which are not filtered or verified before being sent to the Routing Engine, which reduces the speed at which other packets are processed.

Unknown vulnerability in ScreenOS in Juniper Networks NetScreen firewall 3.x through 5.x allows remote attackers to cause a denial of service (device reboot or hang) via a crafted SSH v1 packet.

Fuga de memoria en Juniper JUNOS Packet Forwarding Engine (PFE) permite a atacantes remotos causar una denegación de servicio (consumición de memoria y reinicio del dispositivo) mediante ciertos paquetes IPv6.

TCP, cuando se usa un tamaño de ventana de transmisión grande, hace más fácil a atacantes remotos adivinar números de secuencia y causar una denegación de servicio (pérdida de la conexión) en conexiones TCP persistentes inyectando repetidamente un paquete TCP RST, especialmente en protocolos que usan conexiones de…

Netscreen running ScreenOS 4.0.0r6 and earlier allows remote attackers to cause a denial of service via a malformed SSH packet to the Secure Command Shell (SCS) management interface, as demonstrated via certain CRC32 exploits, a different vulnerability than CVE-2001-0144.

Buffer overflow in NetScreen-Remote 8.0 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted Internet Key Exchange (IKE) response packets, possibly including (1) a large Security Parameter Index (SPI) field, (2) large number of payloads, or (3) a long payload.

Firewalls from multiple vendors empty state tables more slowly than they are filled, which allows remote attackers to flood state tables with packet flooding attacks such as (1) TCP SYN flood, (2) UDP flood, or (3) Crikey CRC Flood, which causes the firewall to refuse any new connections.

El Interfaz web (WebUI) de NetScreen ScreenOS desde la 2.6.1r8 a la anterior a la 3.1.0r1 permite a atacantes remotos causar la Denegación de Servicios (por caida), mediante un nombre largo de usuario.

NetScreen ScreenOS anteriores a 2.6.1 no soporta el establecimiento de un número máximo de sesiones concurrentes para un sistema, lo que permite a un atacante en la red de confianza causar una denegación de servicio (agotamiento de recursos) mediante un escaneo de puertos a una red externa, lo que consume todas las…

NetScreen ScreenOS prior to 2.5r6 on the NetScreen-10 and Netscreen-100 can allow a local attacker to bypass the DMZ 'denial' policy via specific traffic patterns.
