CVE-2021-0298 Description

A Race Condition in the \'show chassis pic\' command in Juniper Networks Junos OS Evolved may allow an attacker to crash the port interface concentrator daemon (picd) process on the FPC, if the command is executed coincident with other system events outside the attacker\'s control, leading to a Denial of Service (DoS) condition.
