CVSS: 6.5EPSS: 0%CPEs: 209EXPL: 0CVE-2022-22191 – Junos OS: EX4300: PFE Denial of Service (DoS) upon receipt of a flood of specific ARP traffic
https://notcve.org/view.php?id=CVE-2022-22191
A Denial of Service (DoS) vulnerability in the processing of a flood of specific ARP traffic in Juniper Networks Junos OS on the EX4300 switch, sent from the local broadcast domain, may allow an unauthenticated network-adjacent attacker to trigger a PFEMAN watchdog timeout, causing the Packet Forwarding Engine (PFE) to crash and restart. After the restart, transit traffic will be temporarily interrupted until the PFE is reprogrammed. In a virtual chassis (VC), the impacted Flexible PIC Concentrator (FPC) may split from the VC temporarily, and join back into the VC once the PFE restarts. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on the EX4300: All versions prior to 15.1R7-S12; 18.4 versions prior to 18.4R2-S10, 18.4R3-S11; 19.1 versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R1-S9, 19.2R3-S4; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R2-S6, 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S1; 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/JSA69502 • CWE-400: Uncontrolled Resource Consumption CWE-410: Insufficient Resource Pool •
CVSS: 7.2EPSS: 0%CPEs: 124EXPL: 0CVE-2022-22186 – Junos OS: EX4650 Series: Certain traffic received by the Junos OS device on the management interface may be forwarded to egress interfaces instead of discarded
https://notcve.org/view.php?id=CVE-2022-22186
Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on EX4650 devices, packets received on the management interface (em0) but not destined to the device, may be improperly forwarded to an egress interface, instead of being discarded. Such traffic being sent by a client may appear genuine, but is non-standard in nature and should be considered as potentially malicious. This issue affects: Juniper Networks Junos OS on EX4650 Series: All versions prior to 19.1R3-S8; 19.2 versions prior to 19.2R3-S5; 19.3 versions prior to 19.3R3-S5; 19.4 versions prior to 19.4R3-S7; 20.1 versions prior to 20.1R3-S3; 20.2 versions prior to 20.2R3-S4; 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.1 versions prior to 21.1R3-S1; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R2; 21.4 versions prior to 21.4R2; 22.1 versions prior to 22.1R1. Debido a una vulnerabilidad de Inicialización Inapropiada en Juniper Networks Junos OS en dispositivos EX4650, los paquetes recibidos en la interfaz de administración (em0), pero que no están destinados al dispositivo, pueden reenviarse incorrectamente a una interfaz de salida, en lugar de descartarse. Este tráfico enviado por un cliente puede parecer genuino, pero no es de naturaleza estándar y debe considerarse como potencialmente malicioso. • https://kb.juniper.net/JSA69494 • CWE-665: Improper Initialization •

https://notcve.org/view.php?id=CVE-2022-22185
A vulnerability in Juniper Networks Junos OS on SRX Series, allows a network-based unauthenticated attacker to cause a Denial of Service (DoS) by sending a specific fragmented packet to the device, resulting in a flowd process crash, which is responsible for packet forwarding. Continued receipt and processing of this specific packet will create a sustained DoS condition. This issue only affects SRX Series when 'preserve-incoming-fragment-size' feature is enabled. This issue affects Juniper Networks Junos OS on SRX Series: 18.3 versions prior to 18.3R3-S6; 18.4 versions prior to 18.4R3-S10; 19.1 versions prior to 19.1R3-S7; 19.2 versions prior to 19.2R3-S4; 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2-S1, 21.1R3; 21.2 versions prior to 21.2R2.

The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. BIND versiones 9.11.0 posteriores a 9.11.36, versiones 9.12.0 posteriores a 9.16.26, versiones 9.17.0 posteriores a 9.18.0, Ediciones Preliminares Soportadas con BIND: versiones .11.4-S1 posteriores a 9.11.36-S1, versiones 9.16.8-S1 posteriores a 9.16.26-S1, también creemos que las versiones de BIND 9 anteriores a las mostradas - hasta la versión 9.1.0, incluyendo las ediciones preliminares soportadas - también están afectadas pero no han sido probadas ya que son EOL. La caché podría envenenarse con registros incorrectos, conllevando a una realización de consultas a servidores erróneos, lo que también podría resultar en que se devolviera información falsa a clientes A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://kb.isc.org/v1/docs/cve-2021-25220 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2SXT7247QTKNBQ67MNRGZD23ADXU6E5U https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5VX3I2U3ICOIEI5Y7OYA6CHOLFMNH3YQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/API7U5E7SX7BAAVFNW366FFJGD6NZZKV https://lists.fedoraproject.org/archives/list/package-announc • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
