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.Show less

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.Show less

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.Show less

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.Show less

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.Show less

NetScreen ScreenOS before 2.6.1 does not support a maximum number of concurrent sessions for a system, which allows an attacker on the trusted network to cause a denial of service (resource exhaustion) via a port scan to an external network, which consumes all available connections.Show less
