https://notcve.org/view.php?id=CVE-2020-1604
On EX4300, EX4600, QFX3500, and QFX5100 Series, a vulnerability in the IP firewall filter component may cause the firewall filter evaluation of certain packets to fail. This issue only affects firewall filter evaluation of certain packets destined to the device Routing Engine (RE). This issue does not affect the Layer 2 firewall filter evaluation nor does it affect the Layer 3 firewall filter evaluation destined to connected hosts. This issue may occur when evaluating both IPv4 or IPv6 packets. This issue affects Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D12 on QFX5100 Series and EX4600 Series; 14.1X53 versions prior to 14.1X53-D52 on QFX3500 Series; 14.1X53 versions prior to 14.1X53-D48 on EX4300 Series; 15.1 versions prior to 15.1R7-S3 on EX4300 Series; 16.1 versions prior to 16.1R7 on EX4300 Series; 17.1 versions prior to 17.1R3 on EX4300 Series; 17.2 versions prior to 17.2R3 on EX4300 Series; 17.3 versions prior to 17.3R2-S5, 17.3R3 on EX4300 Series; 17.4 versions prior to 17.4R2 on EX4300 Series; 18.1 versions prior to 18.1R3 on EX4300 Series; 18.2 versions prior to 18.2R2 on EX4300 Series. • https://kb.juniper.net/JSA10983 • CWE-284: Improper Access Control •
CVSS: 8.6EPSS: 0%CPEs: 119EXPL: 0CVE-2020-1603 – Junos OS: Improper handling of specific IPv6 packets sent by clients eventually kernel crash (vmcore) the device.
https://notcve.org/view.php?id=CVE-2020-1603
Specific IPv6 packets sent by clients processed by the Routing Engine (RE) are improperly handled. These IPv6 packets are designed to be blocked by the RE from egressing the RE. Instead, the RE allows these specific IPv6 packets to egress the RE, at which point a mbuf memory leak occurs within the Juniper Networks Junos OS device. This memory leak eventually leads to a kernel crash (vmcore), or the device hanging and requiring a power cycle to restore service, creating a Denial of Service (DoS) condition. During the time where mbufs are rising, yet not fully filled, some traffic from client devices may begin to be black holed. • https://kb.juniper.net/JSA10982 https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR1443576 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-710: Improper Adherence to Coding Standards •

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 •
