CVE-2019-0009 – Junos OS: EX2300 and EX3400: High disk I/O operations may disrupt the communication between RE and PFE
https://notcve.org/view.php?id=CVE-2019-0009
On EX2300 and EX3400 series, high disk I/O operations may disrupt the communication between the routing engine (RE) and the packet forwarding engine (PFE). In a virtual chassis (VC) deployment, this issue disrupts communication between the VC members. This issue does not affect other Junos platforms. Affected releases are Junos OS on EX2300 and EX3400 series: 15.1X53 versions prior to 15.1X53-D590; 18.1 versions prior to 18.1R2-S2, 18.1R3; 18.2 versions prior to 18.2R2. En las series EX2300 y EX3400, las operaciones high disk I/O podrían interrumpir las comunicaciones entre el motor de enrutamiento (RE) y el motor de reenvío de paquetes (PFE). • http://www.securityfocus.com/bid/106548 https://kb.juniper.net/JSA10909 •

https://notcve.org/view.php?id=CVE-2018-0061
A denial of service vulnerability in the telnetd service on Junos OS allows remote unauthenticated users to cause high CPU usage which may affect system performance. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D81 on SRX Series; 12.3 versions prior to 12.3R12-S11; 12.3X48 versions prior to 12.3X48-D80 on SRX Series; 15.1 versions prior to 15.1R7; 15.1X49 versions prior to 15.1X49-D150, 15.1X49-D160 on SRX Series; 15.1X53 versions prior to 15.1X53-D59 on EX2300/EX3400 Series; 15.1X53 versions prior to 15.1X53-D68 on QFX10K Series; 15.1X53 versions prior to 15.1X53-D235 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D495 on NFX Series; 16.1 versions prior to 16.1R4-S12, 16.1R6-S6, 16.1R7; 16.2 versions prior to 16.2R2-S7, 16.2R3; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R2-S6, 17.2R3; 17.2X75 versions prior to 17.2X75-D100; 17.3 versions prior to 17.3R2-S4, 17.3R3; 17.4 versions prior to 17.4R1-S5, 17.4R2; 18.2X75 versions prior to 18.2X75-D5. Una vulnerabilidad de denegación de servicio (DoS) en el servicio telnetd de Junos OS permite que usuarios remotos no autenticados provoquen un alto uso de la CPU, lo que podría afectar al rendimiento del sistema.

CVE-2018-0054 – QFX5000/EX4600 Series: Routing protocol flap upon receipt of high rate of Ethernet frames
https://notcve.org/view.php?id=CVE-2018-0054
On QFX5000 Series and EX4600 switches, a high rate of Ethernet pause frames or an ARP packet storm received on the management interface (fxp0) can cause egress interface congestion, resulting in routing protocol packet drops, such as BGP, leading to peering flaps. The following log message may also be displayed: fpc0 dcbcm_check_stuck_buffers: Buffers are stuck on queue 7 of port 45 This issue only affects the QFX5000 Series products (QFX5100, QFX5110, QFX5200, QFX5210) and the EX4600 switch. No other platforms are affected by this issue. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D47 on QFX5000 Series and EX4600; 15.1 versions prior to 15.1R7, 15.1R8 on QFX5000 Series and EX4600; 15.1X53 versions prior to 15.1X53-D233 on QFX5000 Series and EX4600; 16.1 versions prior to 16.1R7 on QFX5000 Series and EX4600; 16.2 versions prior to 16.2R3 on QFX5000 Series and EX4600; 17.1 versions prior to 17.1R2-S9, 17.1R3 on QFX5000 Series and EX4600; 17.2 versions prior to 17.2R2-S6, 17.2R3 on QFX5000 Series and EX4600; 17.2X75 versions prior to 17.2X75-D42 on QFX5000 Series and EX4600; 17.3 versions prior to 17.3R3 on QFX5000 Series and EX4600; 17.4 versions prior to 17.4R2 on QFX5000 Series and EX4600; 18.1 versions prior to 18.1R2 on QFX5000 Series and EX4600. En los switches QFX5000 Series y EX4600, una alta tasa de tramas de pausa Ethernet en una tormenta de paquetes ARP recibida en la interfaz de gestión (fxp0) puede provocar una congestión de la interfaz egress, lo que resulta en caídas del paquete del protocolo de enrutamiento, como BGP, lo que conduce a flaps de emparejamiento. • http://www.securitytracker.com/id/1041855 https://kb.juniper.net/JSA10888 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-0052 – Junos OS: Unauthenticated remote root access possible when RSH service is enabled
https://notcve.org/view.php?id=CVE-2018-0052
If RSH service is enabled on Junos OS and if the PAM authentication is disabled, a remote unauthenticated attacker can obtain root access to the device. RSH service is disabled by default on Junos. There is no documented CLI command to enable this service. However, an undocumented CLI command allows a privileged Junos user to enable RSH service and disable PAM, and hence expose the system to unauthenticated root access. When RSH is enabled, the device is listing to RSH connections on port 514. • http://www.securitytracker.com/id/1041853 https://kb.juniper.net/JSA10886 • CWE-287: Improper Authentication •
