CVSS: 7.5EPSS: 0%CPEs: 181EXPL: 0CVE-2022-22185 – Junos OS: SRX Series: Denial of service vulnerability in flowd daemon upon receipt of a specific fragmented packet
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.

https://notcve.org/view.php?id=CVE-2022-22183
An Improper Access Control vulnerability in Juniper Networks Junos OS Evolved allows a network-based unauthenticated attacker who is able to connect to a specific open IPv4 port, which in affected releases should otherwise be unreachable, to cause the CPU to consume all resources as more traffic is sent to the port to create a Denial of Service (DoS) condition. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS Evolved 20.4 versions prior to 20.4R3-S2-EVO; 21.1 versions prior to 21.1R3-S1-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R2-EVO; 21.4 versions prior to 21.4R2-EVO. This issue does not affect Junos OS. Una vulnerabilidad de Control de Acceso Inapropiado en Juniper Networks Junos OS Evolved permite que un atacante no autenticado basado en la red que sea capaz de conectarse a un puerto IPv4 abierto específico, que en las versiones afectadas debería ser inalcanzable de otro modo, cause que la CPU consuma todos los recursos a medida que es enviado más tráfico al puerto para crear una condición de Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69516 • CWE-16: Configuration CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-284: Improper Access Control •

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') •
