"The version of Junos OS installed on the remote host is affected by a vulnerability as referenced in the JSA11212
advisory.
- 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. Continued
execution of the CLI command, under precise conditions, could create a sustained Denial of Service (DoS) condition.
This issue affects all Juniper Networks Junos OS Evolved versions prior to 20.1R2-EVO on PTX10003 and PTX10008
platforms. Junos OS is not affected by this vulnerability. (CVE-2021-0298)
