Description
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).<br />
<br />
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.<br />
This issue affects Junos OS: <br />
<br />

* All versions before 21.2R3-S9, <br />
* from 21.4 before 21.4R3-S10, <br />
