CVE-2019-0055

A vulnerability in the SIP ALG packet processing service of Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the device by sending specific types of valid SIP traffic to the device. In this case, the flowd process crashes and generates a core dump while processing SIP ALG traffic. Continued receipt of these valid SIP packets will result in a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D61, 12.3X48-D65 on SRX Series; 15.1X49 versions prior to 15.1X49-D130 on SRX Series; 17.3 versions prior to 17.3R3 on SRX Series; 17.4 versions prior to 17.4R2 on SRX Series.

Una vulnerabilidad en el servicio de procesamiento de paquetes ALG SIP de Juniper Networks Junos OS, permite a un atacante causar una Denegación de servicio (DoS) al dispositivo mediante el envío de tipos específicos de tráfico SIP válido hacia el dispositivo. En este caso, el proceso flowd se bloquea y genera un volcado de núcleo cuando se procesan el tráfico ALG SIP. La recepción continua de estos paquetes SIP válidos resultará en una condición de denegación de servicio (DoS) sostenida. Este problema afecta a: Juniper Networks OS de Junos: versiones 12.3X48 anteriores a 12.3X48-D61, 12.3X48-D65 en la serie SRX; versiones 15.1X49 anteriores a 15.1X49-D130 en la serie SRX; versiones 17.3 anteriores a 17.3R3 en la serie SRX; versiones 17.4 anteriores a 17.4R2 en la serie SRX.
