Summary
An Improper Check for Unusual or Exceptional Conditions vulnerability in the chassis control daemon (chassisd) of Juniper Networks Junos OS on SRX1500, SRX4100, SRX4200 and SRX4600 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 SRX1500, SRX4100, SRX4200 and SRX4600: • 23.2 versions before 23.2R2-S6, • 23.4 versions before 23.4R2-S7 • 24.2 versions before 24.2R2-S2, • 24.4 versions before 24.4R2, • 25.2 versions before 25.2R1-S1, 25.2R2.
