Descriptions

An Incorrect Calculation of Buffer Size vulnerability in Juniper Networks Junos OS SRX 5000 Series devices using SPC2 line cards while ALGs are enabled allows an attacker sending specific crafted packets to cause a transit traffic Denial of Service (DoS).

Continued receipt and processing of these specific packets will sustain the Denial of Service condition.

This issue affects:
Juniper Networks Junos OS SRX 5000 Series with SPC2 with ALGs enabled.
* All versions earlier than 21.2R3-S7;
* 21.4 versions earlier than 21.4R3-S6;
* 22.1 versions earlier than 22.1R3-S5;
* 22.2 versions earlier than 22.2R3-S3;
* 22.3 versions earlier than 22.3R3-S2;
* 22.4 versions earlier than 22.4R3;
* 23.2 versions earlier than 23.2R2.

Una vulnerabilidad de cálculo incorrecto del tamaño del búfer en dispositivos Juniper Networks Junos OS SRX 5000 Series que utilizan tarjetas de línea SPC2 mientras los ALG están habilitados permite que un atacante envíe paquetes manipulados específicos para provocar una denegación de servicio (DoS) de tráfico de tránsito. La recepción y el procesamiento continuo de estos paquetes específicos mantendrán la condición de Denegación de Servicio. Este problema afecta a: Juniper Networks Junos OS SRX 5000 Series con SPC2 con ALG habilitado. * Todas las versiones anteriores a 21.2R3-S7; * Versiones 21.4 anteriores a 21.4R3-S6; * Versiones 22.1 anteriores a 22.1R3-S5; * Versiones 22.2 anteriores a 22.2R3-S3; * Versiones 22.3 anteriores a 22.3R3-S2; * Versiones 22.4 anteriores a 22.4R3; * Versiones 23.2 anteriores a 23.2R2.
