Name of the Vulnerable Software and Affected Versions Juniper Networks Junos OS on MX, SRX and EX Series versions prior to 22.4R3-S8 Juniper Networks Junos OS on MX, SRX and EX Series versions 23.2 before 23.2R2-S5 Juniper Networks Junos OS on MX, SRX and EX Series versions 23.4 before 23.4R2-S6 Juniper Networks Junos OS on MX, SRX and EX Series versions 24.2 before 24.2R2-S2 Juniper Networks Junos OS on MX, SRX and EX Series versions 24.4 before 24.4R2
Description A NULL Pointer Dereference issue exists in the chassis daemon (chassisd) of Juniper Networks Junos OS on MX, SRX and EX Series. A local attacker with low privileges can trigger a Denial-of-Service (DoS) by executing the 'show chassis' command with specifically crafted options. This causes chassisd to crash and restart, leading to a complete service outage as all components except the Routing Engine (RE) are reinitialized. The system automatically recovers from this outage.
Recommendations Update to Junos OS version 22.4R3-S8 or later. Update to Junos OS version 23.2R2-S5 or later. Update to Junos OS version 23.4R2-S6 or later. Update to Junos OS version 24.2R2-S2 or later. Update to Junos OS version 24.4R2 or later.
