https://notcve.org/view.php?id=CVE-2018-0034
A Denial of Service vulnerability exists in the Juniper Networks Junos OS JDHCPD daemon which allows an attacker to core the JDHCPD daemon by sending a crafted IPv6 packet to the system. This issue is limited to systems which receives IPv6 DHCP packets on a system configured for DHCP processing using the JDHCPD daemon. This issue does not affect IPv4 DHCP packet processing. Affected releases are Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S10 on EX Series; 12.3X48 versions prior to 12.3X48-D70 on SRX Series; 14.1X53 versions prior to 14.1X53-D47 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100; 14.1X53 versions prior to 14.1X53-D130 on QFabric; 15.1 versions prior to 15.1R4-S9, 15.1R6-S6, 15.1R7; 15.1X49 versions prior to 15.1X49-D140 on SRX Series; 15.1X53 versions prior to 15.1X53-D67 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D233 on QFX5110, QFX5200; 15.1X53 versions prior to 15.1X53-D471 on NFX 150, NFX 250; 16.1 versions prior to 16.1R3-S9, 16.1R4-S8, 16.1R5-S4, 16.1R6-S3, 16.1R7; 16.2 versions prior to 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R1-S7, 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S6, 17.2R2-S4, 17.2R3; 17.3 versions prior to 17.3R1-S4, 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R1-S3, 17.4R2.

CVE-2018-0025 – Junos OS: SRX Series: Credentials exposed when using HTTP and HTTPS Firewall Pass-through User Authentication
https://notcve.org/view.php?id=CVE-2018-0025
When an SRX Series device is configured to use HTTP/HTTPS pass-through authentication services, a client sending authentication credentials in the initial HTTP/HTTPS session is at risk that these credentials may be captured during follow-on HTTP/HTTPS requests by a malicious actor through a man-in-the-middle attack or by authentic servers subverted by malicious actors. FTP, and Telnet pass-through authentication services are not affected. Affected releases are Juniper Networks SRX Series: 12.1X46 versions prior to 12.1X46-D67 on SRX Series; 12.3X48 versions prior to 12.3X48-D25 on SRX Series; 15.1X49 versions prior to 15.1X49-D35 on SRX Series. Cuando un dispositivo SRX Series está configurado para emplear los servicios de autenticación pass-through HTTP/HTTPS, un cliente que envía credenciales de autenticación en la sesión inicial HTTP/HTTPS está en riesgo de que estas credenciales puedan ser capturadas durante peticiones HTTP/HTTPS follow-on por parte de un actor malicioso mediante un ataque Man-in-the-Middle (MitM) o por medio de servidores auténticos subvertidos por actores maliciosos. Los servicios de autenticación pass-through FTP y Telnet no se han visto afectados. • http://www.securityfocus.com/bid/104719 http://www.securitytracker.com/id/1041316 https://kb.juniper.net/JSA10858 https://www.juniper.net/documentation/en_US/junos/topics/concept/firewall-user-authentication-pass-through-understanding.html https://www.juniper.net/documentation/en_US/junos/topics/example/firewall-user-authentication-pass-through-configuring-cli.html https://www.juniper.net/documentation/en_US/junos/topics/example/security-https-traffic-to-trigger-pass-through-authentication-configuring.html • CWE-300: Channel Accessible by Non-Endpoint CWE-319: Cleartext Transmission of Sensitive Information •
CVE-2018-0016 – Junos OS: Kernel crash upon receipt of crafted CLNP datagrams
https://notcve.org/view.php?id=CVE-2018-0016
Receipt of a specially crafted Connectionless Network Protocol (CLNP) datagram destined to an interface of a Junos OS device may result in a kernel crash or lead to remote code execution. Devices are only vulnerable to the specially crafted CLNP datagram if 'clns-routing' or ES-IS is explicitly configured. Devices with without CLNS enabled are not vulnerable to this issue. Devices with IS-IS configured on the interface are not vulnerable to this issue unless CLNS routing is also enabled. This issue only affects devices running Junos OS 15.1. • http://www.securityfocus.com/bid/103747 http://www.securitytracker.com/id/1040784 https://kb.juniper.net/JSA10844 •
CVE-2018-0017 – SRX Series: Denial of service vulnerability in flowd daemon on devices configured with NAT-PT
https://notcve.org/view.php?id=CVE-2018-0017
A vulnerability in the Network Address Translation - Protocol Translation (NAT-PT) feature of Junos OS on SRX series devices may allow a certain valid IPv6 packet to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition for the SRX device. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D72; 12.3X48 versions prior to 12.3X48-D55; 15.1X49 versions prior to 15.1X49-D90. Una vulnerabilidad en la característica Network Address Translation - Protocol Translation (NAT-PT) de Junos OS en dispositivos de serie SRX puede permitir que un determinado paquete IPv6 válido cierre inesperadamente el demonio flowd. El cierre inesperado repetido del demonio flowd puede resultar en una condición de denegación de servicio extendida para los dispositivos de la serie SRX. • http://www.securityfocus.com/bid/103749 http://www.securitytracker.com/id/1040785 https://kb.juniper.net/JSA10845 • CWE-20: Improper Input Validation •
CVE-2018-0019 – Junos: Denial of service vulnerability in SNMP MIB-II subagent daemon (mib2d).
https://notcve.org/view.php?id=CVE-2018-0019
A vulnerability in Junos OS SNMP MIB-II subagent daemon (mib2d) may allow a remote network based attacker to cause the mib2d process to crash resulting in a denial of service condition (DoS) for the SNMP subsystem. While a mib2d process crash can disrupt the network monitoring via SNMP, it does not impact routing, switching or firewall functionalities. SNMP is disabled by default on devices running Junos OS. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D76; 12.3 versions prior to 12.3R12-S7, 12.3R13; 12.3X48 versions prior to 12.3X48-D65; 14.1 versions prior to 14.1R9; 14.1X53 versions prior to 14.1X53-D130; 15.1 versions prior to 15.1F2-S20, 15.1F6-S10, 15.1R7; 15.1X49 versions prior to 15.1X49-D130; 15.1X53 versions prior to 15.1X53-D233, 15.1X53-D471, 15.1X53-D472, 15.1X53-D58, 15.1X53-D66; 16.1 versions prior to 16.1R5-S3, 16.1R7; 16.1X65 versions prior to 16.1X65-D47; 16.1X70 versions prior to 16.1X70-D10; 16.2 versions prior to 16.2R1-S6, 16.2R2-S5, 16.2R3; 17.1 versions prior to 17.1R2-S6, 17.1R3; Una vulnerabilidad en el demonio de subagente SNMP MIB-II (mib2d) de Junos OS podría permitir que un atacante remoto en red provoque que el proceso mib2d se cierre inesperadamente, lo que resulta en una condición de denegación de servicio (DoS) para el subsistema SNMP. Aunque un cierre inesperado del proceso mib2d puede interrumpir la monitorización de red mediante SNMP, no impacta sobre las funcionalidades de enrutamiento, switching o firewall. • http://www.securitytracker.com/id/1040787 https://kb.juniper.net/JSA10847 • CWE-20: Improper Input Validation •
