CVSS: 6.5EPSS: 0%CPEs: 274EXPL: 0CVE-2022-22226 – Junos OS: EX4300-MP, EX4600, QFX5000 Series: In VxLAN scenarios specific packets processed cause a memory leak leading to a PFE crash
https://notcve.org/view.php?id=CVE-2022-22226
In VxLAN scenarios on EX4300-MP, EX4600, QFX5000 Series devices an Uncontrolled Memory Allocation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated adjacently located attacker sending specific packets to cause a Denial of Service (DoS) condition by crashing one or more PFE's when they are received and processed by the device. Upon automatic restart of the PFE, continued processing of these packets will cause the memory leak to reappear. Depending on the volume of packets received the attacker may be able to create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on EX4300-MP, EX4600, QFX5000 Series: 17.1 version 17.1R1 and later versions prior to 17.3R3-S12; 17.4 versions prior to 17.4R2-S13, 17.4R3-S5; 18.1 versions prior to 18.1R3-S13; 18.2 versions prior to 18.2R3-S8; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R1-S8, 18.4R2-S6, 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R1-S7, 19.2R3-S1; 19.3 versions prior to 19.3R2-S6, 19.3R3-S1; 19.4 versions prior to 19.4R1-S4, 19.4R2-S4, 19.4R3-S1; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2-S3, 20.2R3; 20.3 versions prior to 20.3R2.

CVSS: 5.9EPSS: 0%CPEs: 92EXPL: 0CVE-2022-22225 – Junos OS and Junos OS Evolved: In a BGP multipath scenario, when one of the contributing routes is flapping often and rapidly, rpd may crash
https://notcve.org/view.php?id=CVE-2022-22225
A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker with an established BGP session to cause a Denial of Service (DoS). In a BGP multipath scenario, when one of the contributing routes is flapping often and rapidly, rpd may crash. As this crash depends on whether a route is a contributing route, and on the internal timing of the events triggered by the flap this vulnerability is outside the direct control of a potential attacker. This issue affects: Juniper Networks Junos OS 19.2 versions prior to 19.2R3-S6; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2; 21.3 versions prior to 21.3R2.

CVSS: 6.5EPSS: 0%CPEs: 125EXPL: 0CVE-2022-22224 – Junos OS and Junos OS Evolved: PPMD goes into infinite loop upon receipt of malformed OSPF TLV
https://notcve.org/view.php?id=CVE-2022-22224
An Improper Check or Handling of Exceptional Conditions vulnerability in the processing of a malformed OSPF TLV in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause the periodic packet management daemon (PPMD) process to go into an infinite loop, which in turn can cause protocols and functions reliant on PPMD such as OSPF neighbor reachability to be impacted, resulting in a sustained Denial of Service (DoS) condition. The DoS condition persists until the PPMD process is manually restarted. This issue affects: Juniper Networks Junos OS: All versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S3; 19.4 versions prior to 19.4R3-S9; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S1; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS Evolved: All versions prior to 20.4R3-S3-EVO; 21.1 versions prior to 21.1R2-EVO. Una vulnerabilidad de comprobación o administración inapropiada de condiciones excepcionales en el procesamiento de un TLV OSPF malformado en Juniper Networks Junos OS y Junos OS Evolved permite a un atacante adyacente no autenticado causar que el proceso del demonio de administración de paquetes periódicos (PPMD) entre en un bucle infinito, lo que a su vez puede causar que los protocolos y las funciones que dependen de PPMD, como la accesibilidad de los vecinos de OSPF, estén afectados, resultando en una condición de Denegación de Servicio (DoS) sostenida. • https://kb.juniper.net/JSA69874 • CWE-703: Improper Check or Handling of Exceptional Conditions •
CVSS: 7.5EPSS: 0%CPEs: 225EXPL: 1CVE-2022-22223 – Junos OS: QFX10000 Series: In IP/MPLS PHP node scenarios upon receipt of certain crafted packets multiple interfaces in LAG configurations may detach.
https://notcve.org/view.php?id=CVE-2022-22223
On QFX10000 Series devices using Juniper Networks Junos OS when configured as transit IP/MPLS penultimate hop popping (PHP) nodes with link aggregation group (LAG) interfaces, an Improper Validation of Specified Index, Position, or Offset in Input weakness allows an attacker sending certain IP packets to cause multiple interfaces in the LAG to detach causing a Denial of Service (DoS) condition. Continued receipt and processing of these packets will sustain the Denial of Service. This issue affects IPv4 and IPv6 packets. Packets of either type can cause and sustain the DoS event. These packets can be destined to the device or be transit packets. • https://kb.juniper.net/JSA69873 • CWE-20: Improper Input Validation CWE-1285: Improper Validation of Specified Index, Position, or Offset in Input •
CVSS: 5.9EPSS: 0%CPEs: 92EXPL: 0CVE-2022-22220 – Junos OS and Junos OS Evolved: Due to a race condition the rpd process can crash upon receipt of a BGP update message containing flow spec route
https://notcve.org/view.php?id=CVE-2022-22220
A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Routing Protocol Daemon (rpd) of Juniper Networks Junos OS, Junos OS Evolved allows a network-based unauthenticated attacker to cause a Denial of Service (DoS). When a BGP flow route with redirect IP extended community is received, and the reachability to the next-hop of the corresponding redirect IP is flapping, the rpd process might crash. Whether the crash occurs depends on the timing of the internally processing of these two events and is outside the attackers control. Please note that this issue also affects Route-Reflectors unless 'routing-options flow firewall-install-disable' is configured. This issue affects: Juniper Networks Junos OS: 18.4 versions prior to 18.4R2-S10, 18.4R3-S10; 19.1 versions prior to 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.4 versions prior to 19.4R3-S8; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. • https://kb.juniper.net/JSA69902 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
