CVE-2022-22175

An Improper Locking vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series and SRX Series allows an unauthenticated networked attacker to cause a flowprocessing daemon (flowd) crash and thereby a Denial of Service (DoS). Continued receipt of these specific packets will cause a sustained Denial of Service condition. This issue can occur in a scenario where the SIP ALG is enabled and specific SIP messages are being processed simultaneously. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R2-S2, 21.1R3; 21.2 versions prior to 21.2R1-S2, 21.2R2; 21.3 versions prior to 21.3R1-S1, 21.3R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1.

Una vulnerabilidad de bloqueo inapropiado en el SIP ALG de Juniper Networks Junos OS en las series MX y SRX permite a un atacante no autenticado en red causar un bloqueo del demonio de procesamiento de flujos (flowd) y, por tanto, una denegación de servicio (DoS). La recepción continuada de estos paquetes específicos causará una condición de denegación de servicio sostenida. Este problema puede producirse en un escenario en el que la SIP ALG esté habilitada y estén procesándose simultáneamente mensajes SIP específicos. Este problema afecta a: Juniper Networks Junos OS en las series MX y SRX versiones anteriores a 20.4R3-S1; versiones 21.1 anteriores a 21.1R2-S2, 21.1R3; versiones 21.2 anteriores a 21.2R1-S2, 21.2R2; versiones 21.3 anteriores a 21.3R1-S1, 21.3R2. Este problema no afecta a versiones del Sistema Operativo Junos de Juniper Networks anteriores a 20.4R1
