CWE	https://cwe.mitre.org/data/definitions/755.html

An Improper Handling of Exceptional Conditions vulnerability in routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker executing a CLI command to cause a Denial of Service (DoS).

When asregex-optimized is configured and a specific show route as-path CLI command is executed, the rpd crashes and restarts. Repeated execution of this command will cause a sustained DoS condition. This issue affects Junos OS:

from 22.2 before 22.2R3-S6,
