An Improper Check for Unusual or Exceptional Conditions vulnerability in the chassis control daemon (chassisd) of Juniper Networks Junos OS on SRX1600, SRX2300 and SRX4300 allows a local attacker with low privileges to cause a complete Denial of Service (DoS).
When a specific 'show chassis' CLI command is executed, chassisd crashes and restarts which causes a momentary impact to all traffic until all modules are online again.
This issue affects Junos OS on SRX1600, SRX2300 and SRX4300:
* 24.4 versions before 24.4R1-S3, 24.4R2.
This issue does not affect Junos OS versions before 24.4R1.
