CVE-2022-22213 – Junos OS and Junos OS Evolved: Denial of Service (DoS) vulnerability in RPD upon receipt of specific BGP update
https://notcve.org/view.php?id=CVE-2022-22213
A vulnerability in Handling of Undefined Values in the routing protocol daemon (RPD) process of Juniper Networks Junos OS and Junos OS Evolved may allow an unauthenticated network-based attacker to crash the RPD process by sending a specific BGP update while the system is under heavy load, leading to a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Malicious exploitation of this issue requires a very specific combination of load, timing, and configuration of the vulnerable system which is beyond the direct control of the attacker. Internal reproduction has only been possible through artificially created load and specially instrumented source code. Systems are only vulnerable to this issue if BGP multipath is enabled. • https://kb.juniper.net/JSA69717 • CWE-232: Improper Handling of Undefined Values •
CVE-2022-22210 – Junos OS: QFX5000 Series and MX Series: An l2alm crash leading to an FPC crash can be observed in VxLAN scenario
https://notcve.org/view.php?id=CVE-2022-22210
A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX5000 Series and MX Series allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). On QFX5K Series and MX Series, when the PFE receives a specific VxLAN packet the Layer 2 Address Learning Manager (L2ALM) process will crash leading to an FPC reboot. Continued receipt of this specific packet will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on QFX5000 Series, MX Series: 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.2 versions prior to 21.2R2-S1. This issue does not affect Juniper Networks Junos OS: All versions prior to 20.3R1; 21.1 version 21.1R1 and later versions. • https://kb.juniper.net/JSA69714 • CWE-476: NULL Pointer Dereference •
CVE-2022-22207 – Junos OS: MX Series with MPC11: In a GNF / node slicing scenario gathering AF interface statistics can lead to a kernel crash
https://notcve.org/view.php?id=CVE-2022-22207
A Use After Free vulnerability in the Advanced Forwarding Toolkit (AFT) manager process (aftmand) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause a kernel crash due to intensive polling of Abstracted Fabric (AF) interface statistics and thereby a Denial of Service (DoS). Continued gathering of AF interface statistics will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on MX Series: 20.1 versions later than 20.1R1; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S4; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2; 21.2 versions prior to 21.2R2. Una vulnerabilidad de Uso de Memoria Previamente Liberada en el proceso de administración de Advanced Forwarding Toolkit (AFT) (aftmand) de Juniper Networks Junos OS permite a un atacante no autenticado en red causar un bloqueo del kernel debido al sondeo intensivo de las estadísticas de la interfaz de Abstracted Fabric (AF) y, por tanto, una Denegación de Servicio (DoS). La recopilación continuada de estadísticas de la interfaz AF creará una condición de Denegación de Servicio (DoS) sostenida. • https://kb.juniper.net/JSA69711 • CWE-416: Use After Free •
CVE-2022-22206 – Junos OS: SRX series: The PFE will crash when specific traffic is scanned by Enhanced Web Filtering safe-search
https://notcve.org/view.php?id=CVE-2022-22206
A Buffer Overflow vulnerability in the PFE of Juniper Networks Junos OS on SRX series allows an unauthenticated network based attacker to cause a Denial of Service (DoS). The PFE will crash when specific traffic is scanned by Enhanced Web Filtering safe-search feature of UTM (Unified Threat management). Continued receipt of this specific traffic will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: 20.2 versions prior to 20.2R3-S4 on SRX Series; 20.3 versions prior to 20.3R3-S3 on SRX Series; 20.4 versions prior to 20.4R3-S3 on SRX Series; 21.1 versions prior to 21.1R3-S1 on SRX Series; 21.2 versions prior to 21.2R2-S2, 21.2R3 on SRX Series; 21.3 versions prior to 21.3R2 on SRX Series; 21.4 versions prior to 21.4R2 on SRX Series. This issue does not affect Juniper Networks Junos OS versions prior to 20.2R1. • https://kb.juniper.net/JSA69710 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2022-22205 – Junos OS: SRX Series: An FPC memory leak can occur in an APBR scenario
https://notcve.org/view.php?id=CVE-2022-22205
A Missing Release of Memory after Effective Lifetime vulnerability in the Application Quality of Experience (appqoe) subsystem of the PFE of Juniper Networks Junos OS on SRX Series allows an unauthenticated network based attacker to cause a Denial of Service (DoS). Upon receiving specific traffic a memory leak will occur. Sustained processing of such specific traffic will eventually lead to an out of memory condition that prevents all services from continuing to function, and requires a manual restart to recover. A device is only vulnerable when advance(d) policy based routing (APBR) is configured and AppQoE (sla rule) is not configured for these APBR rules. This issue affects Juniper Networks Junos OS on SRX Series: 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2-S1, 21.2R3; 21.3 versions prior to 21.3R1-S2, 21.3R2. • https://kb.juniper.net/JSA69709 • CWE-401: Missing Release of Memory after Effective Lifetime •
