A Stack-based Buffer Overflow vulnerability in the CLI command of Juniper Networks Junos and Junos EVO allows a low privileged attacker to execute a specific CLI commands leading to Denial of Service.
Repeated actions by the attacker will create a sustained Denial of Service (DoS) condition.
This issue affects Juniper Networks:
Junos OS:
* All versions prior to 19.1R3-S10;
* 19.2 versions prior to 19.2R3-S7;
* 19.3 versions prior to 19.3R3-S8;
* 19.4 versions prior to 19.4R3-S12;

* 22.2 versions prior to 22.2R3-S1;
* 22.3 versions prior to 22.3R3;
* 22.4 versions prior to 22.4R2.
