CVE-2005-4587 1 Juniper 1 Netscreen-security Manager 2004 2026-06-16 7.8 HIGH N/A
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).
CVE-2005-3733 1 Juniper 8 Junos E, Junos J, Junos M and 5 more 2026-06-16 7.5 HIGH N/A
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 PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.
CVE-2005-2640 3 Juniper, Neoteris, Netscreen 16 Netscreen-5gt, Netscreen-idp, Netscreen-idp 10 and 13 more 2026-06-16 5.0 MEDIUM N/A
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 the username is invalid.
CVE-2004-1766 1 Juniper 1 Netscreen-security Manager 2004 2026-06-16 5.0 MEDIUM N/A
The default installation of NetScreen-Security Manager before Feature Pack 1 does not enable encryption for communication with devices running ScreenOS 5.0, which allows remote attackers to obtain sensitive information via sniffing.
CVE-2004-1446 1 Juniper 1 Netscreen Screenos 2026-06-16 5.0 MEDIUM N/A
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.
CVE-2004-0468 1 Juniper 1 Junos 2026-06-16 5.0 MEDIUM N/A
Memory leak in Juniper JUNOS Packet Forwarding Engine (PFE) allows remote attackers to cause a denial of service (memory exhaustion and device reboot) via certain IPv6 packets.
CVE-2004-0467 1 Juniper 1 Junos 2026-06-16 5.0 MEDIUM N/A
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.
CVE-2002-2223 1 Juniper 2 Netscreen Remote Security Client, Netscreen Remote Vpn Client 2026-06-16 5.1 MEDIUM N/A
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.
CVE-2002-2150 1 Juniper 1 Netscreen Screenos 2026-06-16 5.0 MEDIUM N/A
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.
CVE-2002-1547 1 Juniper 1 Netscreen Screenos 2026-06-16 5.0 MEDIUM N/A
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.
CVE-2002-0891 1 Juniper 1 Netscreen Screenos 2026-06-16 5.0 MEDIUM N/A
The web interface (WebUI) of NetScreen ScreenOS before 2.6.1r8, and certain 2.8.x and 3.0.x versions before 3.0.3r1, allows remote attackers to cause a denial of service (crash) via a long user name.
CVE-2002-0234 1 Juniper 1 Netscreen Screenos 2026-06-16 2.1 LOW N/A
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.
CVE-2001-0589 1 Juniper 1 Netscreen Screenos 2026-06-16 2.1 LOW N/A
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.
