Descriptions
A Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in the Flow-processing Daemon (flowd) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (Dos).
On SRX Series devices when two different threads try to simultaneously process a queue which is used for TCP events flowd will crash. One of these threads can not be triggered externally, so the exploitation of this race condition is outside the attackers direct control.
Continued exploitation of this issue will lead to a sustained DoS.
This issue affects Juniper Networks Junos OS:
* 21.2 versions earlier than 21.2R3-S5;
* 21.3 versions earlier than 21.3R3-S5;
* 21.4 versions earlier than 21.4R3-S4;
* 22.1 versions earlier than 22.1R3-S3;
* 22.2 versions earlier than 22.2R3-S1;
* 22.3 versions earlier than 22.3R2-S2, 22.3R3;
* 22.4 versions earlier than 22.4R2-S1, 22.4R3.
This issue does not affect Juniper Networks Junos OS versions earlier than 21.2R1.
Una vulnerabilidad de ejecución concurrente que utiliza recurso compartido con sincronización inadecuada ('condición de ejecución') en Flow-processing Daemon (flowd) de Juniper Networks Junos OS en la serie SRX permite que un atacante basado en red no autenticado provoque una denegación de servicio ( Dos). En los dispositivos de la serie SRX, cuando dos subprocesos diferentes intentan procesar simultáneamente una cola que se utiliza para el flujo de eventos TCP, se bloqueará. Uno de estos subprocesos no se puede activar externamente, por lo que la explotación de esta condición de ejecución está fuera del control directo del atacante. La explotación continua de este problema conducirá a un DoS sostenido. Este problema afecta a Juniper Networks Junos OS: * Versiones 21.2 anteriores a 21.2R3-S5; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S4; * Versiones 22.1 anteriores a 22.1R3-S3; * Versiones 22.2 anteriores a 22.2R3-S1; * Versiones 22.3 anteriores a 22.3R2-S2, 22.3R3; * Versiones 22.4 anteriores a 22.4R2-S1, 22.4R3. Este problema no afecta a las versiones de Juniper Networks Junos OS anteriores a la 21.2R1.
