CVE-2022-22230 – Junos OS and Junos OS Evolved: RPD crash upon receipt of specific OSPFv3 LSAs

https://notcve.org/view.php?id=CVE-2022-22230

An Improper Input Validation vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause DoS (Denial of Service). If another router generates more than one specific valid OSPFv3 LSA then rpd will crash while processing these LSAs. This issue only affects systems configured with OSPFv3, while OSPFv2 is not affected. This issue affects: Juniper Networks Junos OS 19.2 versions prior to 19.2R3-S6; 19.3 version 19.3R2 and later versions; 19.4 versions prior to 19.4R2-S8, 19.4R3-S9; 20.1 version 20.1R1 and later versions; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3-S2; 21.4 versions prior to 21.4R2.

CVE-2022-22228 – Junos OS: IPv6 OAM SRv6 network-enabled devices are vulnerable to Denial of Service (DoS) due to RPD memory leak upon receipt of specific a IPv6 packet

https://notcve.org/view.php?id=CVE-2022-22228

An Improper Validation of Specified Type of Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS allows an attacker to cause an RPD memory leak leading to a Denial of Service (DoS). This memory leak only occurs when the attacker's packets are destined to any configured IPv6 address on the device. This issue affects: Juniper Networks Junos OS 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 21.1R1. Una vulnerabilidad de comprobación inapropiada del tipo de entrada especificado en el demonio de protocolo de enrutamiento (rpd) del Juniper Networks Junos OS permite a un atacante causar una pérdida de memoria en el RPD conllevando a una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69880 • CWE-20: Improper Input Validation CWE-1287: Improper Validation of Specified Type of Input •

CVE-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.

CVE-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. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S4-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO versions prior to 21.2R2-EVO; 21.3-EVO versions prior to 21.3R2-EVO. • https://kb.juniper.net/JSA69875 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

CVE-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 •
