CVE-2020-1600 – Junos OS: A specific SNMP command can trigger a high CPU usage Denial of Service in the RPD daemon.
https://notcve.org/view.php?id=CVE-2020-1600
In a Point-to-Multipoint (P2MP) Label Switched Path (LSP) scenario, an uncontrolled resource consumption vulnerability in the Routing Protocol Daemon (RPD) in Juniper Networks Junos OS allows a specific SNMP request to trigger an infinite loop causing a high CPU usage Denial of Service (DoS) condition. This issue affects both SNMP over IPv4 and IPv6. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D90; 15.1 versions prior to 15.1R7-S6; 15.1X49 versions prior to 15.1X49-D200; 15.1X53 versions prior to 15.1X53-D238, 15.1X53-D592; 16.1 versions prior to 16.1R7-S5; 16.2 versions prior to 16.2R2-S11; 17.1 versions prior to 17.1R3-S1; 17.2 versions prior to 17.2R3-S2; 17.3 versions prior to 17.3R3-S7; 17.4 versions prior to 17.4R2-S4, 17.4R3; 18.1 versions prior to 18.1R3-S5; 18.2 versions prior to 18.2R3; 18.2X75 versions prior to 18.2X75-D50; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R2. En un escenario Point-to-Multipoint (P2MP) Label Switched Path (LSP), una vulnerabilidad de consumo de recursos no controlada en el Routing Protocol Daemon (RPD) en Juniper Networks Junos OS permite que una petición SNMP específica active un bucle infinito causando a una CPU en uso una alta condición de Denegación de Servicio (DoS). Este problema afecta tanto a SNMP sobre IPv4 como a IPv6. • https://kb.juniper.net/JSA10979 https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR1402185 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2019-0075 – Junos OS: SRX Series: Denial of Service vulnerability in srxpfe related to PIM
https://notcve.org/view.php?id=CVE-2019-0075
A vulnerability in the srxpfe process on Protocol Independent Multicast (PIM) enabled SRX series devices may lead to crash of the srxpfe process and an FPC reboot while processing (PIM) messages. Sustained receipt of these packets may lead to an extended denial of service condition. Affected releases are Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D80; 15.1X49 versions prior to 15.1X49-D160; 17.3 versions prior to 17.3R3-S7 17.4 versions prior to 17.4R2-S8, 17.4R3; 18.1 versions prior to 18.1R3-S8; 18.2 versions prior to 18.2R2; 18.3 versions prior to 18.3R2. Una vulnerabilidad en el proceso srxpfe en los dispositivos de la Serie SRX con Protocol Independent Multicast (PIM) habilitado, puede conllevar al bloqueo del proceso srxpfe y un reinicio de FPC durante el procesamiento de mensajes (PIM). La recepción sostenida de estos paquetes puede conllevar a una condición de denegación de servicio extendida. • https://kb.juniper.net/JSA10976 •
CVE-2019-0074 – Junos OS: NFX150 Series, QFX10K Series, EX9200 Series, MX Series, PTX Series: Path traversal vulnerability in NFX150 and NG-RE leads to information disclosure.

CVE-2019-0071 – Junos OS: EX2300, EX3400 Series: Veriexec signature checking not enforced in specific versions of Junos OS
https://notcve.org/view.php?id=CVE-2019-0071
Veriexec is a kernel-based file integrity subsystem in Junos OS that ensures only authorized binaries are able to be executed. Due to a flaw in specific versions of Junos OS, affecting specific EX Series platforms, the Veriexec subsystem will fail to initialize, in essence disabling file integrity checking. This may allow a locally authenticated user with shell access to install untrusted executable images, and elevate privileges to gain full control of the system. During the installation of an affected version of Junos OS are installed, the following messages will be logged to the console: Initializing Verified Exec: /sbin/veriexec: Undefined symbol "__aeabi_uidiv" /sbin/veriexec: Undefined symbol "__aeabi_uidiv" /sbin/veriexec: Undefined symbol "__aeabi_uidiv" veriexec: /.mount/packages/db/os-kernel-prd-arm-32-20190221.70c2600_builder_stable_11/boot/brcm-hr3.dtb: Authentication error veriexec: /.mount/packages/db/os-kernel-prd-arm-32-20190221.70c2600_builder_stable_11/boot/contents.izo: Authentication error ...
