Vulnerability from fkie_nvd - Published: 2025-04-09 20:15 - Updated: 2025-04-11 15:40
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A NULL Pointer Dereference vulnerability in the flow daemon (flowd) of Juniper Networks Junos OS on SRX Series allows an attacker causing specific, valid control traffic to be sent out of a Dual-Stack (DS) Lite tunnel to crash the flowd process, resulting in a Denial of Service (DoS).  Continuous triggering of specific control traffic will create a sustained Denial of Service (DoS) condition. On all SRX platforms, when specific, valid control traffic needs to be sent out of a DS-Lite tunnel, a segmentation fault occurs within the flowd process, resulting in a network outage until the flowd process restarts. This issue affects Junos OS on SRX Series: * All versions before 21.2R3-S9, * from 21.4 before 21.4R3-S9, * from 22.2 before 22.2R3-S5, * from 22.4 before 22.4R3-S6, * from 23.2 before 23.2R2-S3, * from 23.4 before 23.4R2.

      "value": "Una vulnerabilidad de desreferencia de puntero nulo en el demonio de flujo (flowd) de Juniper Networks Junos OS en la serie SRX permite que un atacante, al enviar tr\u00e1fico de control v\u00e1lido y espec\u00edfico desde un t\u00fanel Dual-Stack (DS) Lite, bloquee el proceso flowd, lo que resulta en una denegaci\u00f3n de servicio (DoS). La activaci\u00f3n continua de tr\u00e1fico de control espec\u00edfico crea una condici\u00f3n de denegaci\u00f3n de servicio (DoS) sostenida. En todas las plataformas SRX, cuando se necesita enviar tr\u00e1fico de control v\u00e1lido y espec\u00edfico desde un t\u00fanel DS-Lite, se produce un fallo de segmentaci\u00f3n dentro del proceso flowd, lo que provoca una interrupci\u00f3n de la red hasta que este se reinicia. Este problema afecta a Junos OS en la serie SRX: * Todas las versiones anteriores a 21.2R3-S9, * desde 21.4 hasta 21.4R3-S9, * desde 22.2 hasta 22.2R3-S5, * desde 22.4 hasta 22.4R3-S6, * desde 23.2 hasta 23.2R2-S3, * desde 23.4 hasta 23.4R2."
