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 •
CVE-2022-22204 – Junos OS: MX Series and SRX Series: When receiving a specific SIP packets stale call table entries are created which eventually leads to a DoS for all SIP traffic
https://notcve.org/view.php?id=CVE-2022-22204
An Improper Release of Memory Before Removing Last Reference vulnerability in the Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Juniper Networks Junos OS allows unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On all MX and SRX platforms, if the SIP ALG is enabled, receipt of a specific SIP packet will create a stale SIP entry. Sustained receipt of such packets will cause the SIP call table to eventually fill up and cause a DoS for all SIP traffic. The SIP call usage can be monitored by "show security alg sip calls". To be affected the SIP ALG needs to be enabled, either implicitly / by default or by way of configuration. • https://kb.juniper.net/JSA69708 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2022-22202 – Junos OS: PTX Series: FPCs may restart unexpectedly upon receipt of specific MPLS packets with certain multi-unit interface configurations
https://notcve.org/view.php?id=CVE-2022-22202
An Improper Handling of Exceptional Conditions vulnerability on specific PTX Series devices, including the PTX1000, PTX3000 (NextGen), PTX5000, PTX10002-60C, PTX10008, and PTX10016 Series, in Juniper Networks Junos OS allows an unauthenticated MPLS-based attacker to cause a Denial of Service (DoS) by triggering the dcpfe process to crash and FPC to restart. On affected PTX Series devices, processing specific MPLS packets received on an interface with multiple units configured may cause FPC to restart unexpectedly. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects PTX Series devices utilizing specific FPCs found on PTX1000, PTX3000 (NextGen), PTX5000, PTX10002-60C, PTX10008, and PTX10016 Series devices, only if multiple units are configured on the ingress interface, and at least one unit has 'family mpls' *not* configured. See the configuration sample below for more information. • https://kb.juniper.net/JSA69706 • CWE-755: Improper Handling of Exceptional Conditions •
