Descriptions
An Improper Check for Unusual or Exceptional Conditions vulnerability in Juniper DHCP Daemon (jdhcpd) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause the jdhcpd to consume all the CPU cycles resulting in a Denial of Service (DoS).
On Junos OS devices with forward-snooped-client configured, if an attacker sends a specific DHCP packet to a non-configured interface, this will cause an infinite loop. The DHCP process will have to be restarted to recover the service.
This issue affects:
Juniper Networks Junos OS
* All versions earlier than 20.4R3-S9;
* 21.2 versions earlier than 21.2R3-S7;
* 21.3 versions earlier than 21.3R3-S5;
* 21.4 versions earlier than 21.4R3-S5;
* 22.1 versions earlier than 22.1R3-S4;
* 22.2 versions earlier than 22.2R3-S3;
* 22.3 versions earlier than 22.3R3-S2;
* 22.4 versions earlier than 22.4R2-S2, 22.4R3;
* 23.2 versions earlier than 23.2R2.
Una verificación inadecuada de la vulnerabilidad de condiciones inusuales o excepcionales en Juniper DHCP Daemon (jdhcpd) de Juniper Networks Junos OS permite que un atacante adyacente no autenticado haga que jdhcpd consuma todos los ciclos de la CPU, lo que resulta en una denegación de servicio (DoS). En dispositivos Junos OS con forward-snooped-client configurado, si un atacante envía un paquete DHCP específico a una interfaz no configurada, esto provocará un bucle infinito. Será necesario reiniciar el proceso DHCP para recuperar el servicio. Este problema afecta a: Juniper Networks Junos OS * Todas las versiones anteriores a 20.4R3-S9; * Versiones 21.2 anteriores a 21.2R3-S7; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S5; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3-S3; * Versiones 22.3 anteriores a 22.3R3-S2; * Versiones 22.4 anteriores a 22.4R2-S2, 22.4R3; * Versiones 23.2 anteriores a 23.2R2.
