TITLE

Juniper Networks Junos Vulnerabilities related to resource exhaustion

Trust: 0.8

sources: JVNDB: JVNDB-2019-006593

DESCRIPTION

A vulnerability in the pfe-chassisd Chassis Manager (CMLC) daemon of Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the EX4300 when specific valid broadcast packets create a broadcast storm condition when received on the me0 interface of the EX4300 Series device. A reboot of the device is required to restore service. Continued receipt of these valid broadcast packets will create a sustained Denial of Service (DoS) against the device. Affected releases are Juniper Networks Junos OS: 16.1 versions above and including 16.1R1 prior to 16.1R7-S5; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S2; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2. Juniper Networks Junos Contains a resource exhaustion vulnerability.Denial of service (DoS) May be in a state. Juniper Junos is prone to a denial-of-service vulnerability. An attacker may exploit this issue to cause denial-of-service conditions. Juniper Networks Junos OS is a set of network operating system of Juniper Networks (Juniper Networks) dedicated to the company's hardware equipment.
