CVSS: 7.5EPSS: 0%CPEs: 144EXPL: 0CVE-2020-1601 – Junos OS: Upon receipt of certain types of malformed PCEP packets the pccd process may crash.
https://notcve.org/view.php?id=CVE-2020-1601
Certain types of malformed Path Computation Element Protocol (PCEP) packets when received and processed by a Juniper Networks Junos OS device serving as a Path Computation Client (PCC) in a PCEP environment using Juniper's path computational element protocol daemon (pccd) process allows an attacker to cause the pccd process to crash and generate a core file thereby causing a Denial of Service (DoS). Continued receipt of this family of malformed PCEP packets will cause an extended Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S13, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D180 on SRX Series; 15.1X53 versions prior to 15.1X53-D238, 15.1X53-D496, 15.1X53-D592; 16.1 versions prior to 16.1R7-S4; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R2-S11, 17.1R3; 17.2 versions prior to 17.2R1-S9; 17.2 version 17.2R2 and later prior to 17.2R3-S2; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R2-S2, 17.4R3; 18.1 versions prior to 18.1R3-S2; 18.2 versions prior to 18.2R2-S6, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2. This issue does not affect releases of Junos OS prior to 15.1R1. Ciertos tipos de paquetes Path Computation Element Protocol (PCEP) malformados cuando son recibidos y procesados por un dispositivo Juniper Networks Junos OS que sirve como un Path Computation Client (PCC) en un entorno PCEP utilizando el proceso path computational element protocol daemon (pccd) de Juniper permite a un atacante causar que el proceso pccd se bloquee y genere un archivo central, causando una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA10980 https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR1395205 •
CVSS: 7.5EPSS: 0%CPEs: 230EXPL: 0CVE-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 •
CVSS: 7.5EPSS: 0%CPEs: 301EXPL: 0CVE-2019-0068 – Junos OS: SRX Series: Denial of Service vulnerability in flowd due to multicast packets
https://notcve.org/view.php?id=CVE-2019-0068
The SRX flowd process, responsible for packet forwarding, may crash and restart when processing specific multicast packets. By continuously sending the specific multicast packets, an attacker can repeatedly crash the flowd process causing a sustained Denial of Service. This issue affects Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D90; 15.1X49 versions prior to 15.1X49-D180; 17.3 versions; 17.4 versions prior to 17.4R2-S5, 17.4R3; 18.1 versions prior to 18.1R3-S6; 18.2 versions prior to 18.2R2-S4, 18.2R3; 18.3 versions prior to 18.3R2-S1, 18.3R3; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R1-S1, 19.1R2. El proceso flowd SRX, responsable del reenvío de paquetes, puede bloquearse y reiniciarse cuando se procesan paquetes de multidifusión específicos. Mediante el envío de manera continua de los paquetes de multidifusión específicos, un atacante puede bloquear repetidamente el proceso flowd causando una Denegación de Servicio sostenida. • https://kb.juniper.net/JSA10968 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 7.5EPSS: 0%CPEs: 132EXPL: 0CVE-2019-0066 – Junos OS: A malformed IPv4 packet received by Junos in an NG-mVPN scenario may cause the routing protocol daemon (rpd) process to core
https://notcve.org/view.php?id=CVE-2019-0066
An unexpected status return value weakness in the Next-Generation Multicast VPN (NG-mVPN) service of Juniper Networks Junos OS allows attacker to cause a Denial of Service (DoS) condition and core the routing protocol daemon (rpd) process when a specific malformed IPv4 packet is received by the device running BGP. This malformed packet can be crafted and sent to a victim device including when forwarded directly through a device receiving such a malformed packet, but not if the malformed packet is first de-encapsulated from an encapsulated format by a receiving device. Continued receipt of the malformed packet will result in a sustained Denial of Service condition. This issue affects: Juniper Networks Junos OS 15.1 versions prior to 15.1F6-S12, 15.1R7-S2; 15.1X49 versions prior to 15.1X49-D150 on SRX Series; 15.1X53 versions prior to 15.1X53-D68, 15.1X53-D235, 15.1X53-D495, 15.1X53-D590; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S2; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R2-S6, 17.2R3; 17.3 versions prior to 17.3R2-S4, 17.3R3. Una debilidad de valor de retorno de estado inesperado en el Next-Generation Multicast VPN (NG-mVPN) de Juniper Networks Junos OS, permite al atacante causar una condición de denegación de servicio (DoS) y centrar el proceso del demonio del protocolo de enrutamiento (rpd) cuando un paquete IPv4 malformado específico es recibido por parte del dispositivo que ejecuta BGP. • https://kb.juniper.net/JSA10965 https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/ng-mvpn-services-enabling.html • CWE-394: Unexpected Status Code or Return Value •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2019-0064 – Junos OS: SRX5000 Series: flowd process crash due to receipt of specific TCP packet
https://notcve.org/view.php?id=CVE-2019-0064
On SRX5000 Series devices, if 'set security zones security-zone <zone> tcp-rst' is configured, the flowd process may crash when a specific TCP packet is received by the device and triggers a new session. The process restarts automatically. However, receipt of a constant stream of these TCP packets may result in an extended Denial of Service (DoS) condition on the device. This issue affects Juniper Networks Junos OS: 18.2R3 on SRX 5000 Series; 18.4R2 on SRX 5000 Series; 19.2R1 on SRX 5000 Series. En los dispositivos de la Serie SRX5000, si se configura "set security zones security-zone (zone) tcp-rst", el proceso flowd puede bloquearse cuando un paquete TCP específico es recibido por el dispositivo y desencadena una nueva sesión. • https://kb.juniper.net/JSA10963 •
