Description The issue is related to an Improper Validation of Array Index vulnerability in the Advanced Forwarding Toolkit Manager daemon (aftmand) of Juniper Networks Junos OS and Junos OS Evolved. This allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). On specific platforms, querying a certain SNMP MIB can cause a PFE crash, resulting in the FPC going offline and requiring a system restart to recover.

For Junos OS version 22.2, update to version 22.2R2 or later. For Junos OS Evolved version 21.3R3-EVO, update to a version later than 21.3R3-EVO. For Junos OS Evolved version 21.4R1-S2-EVO, update to version 21.4R2-S1-EVO or later. For Junos OS Evolved version 21.4R2-EVO, update to version 21.4R2-S1-EVO or later. For Junos OS Evolved version 22.1R2-EVO, update to version 22.1R3-EVO or later. For Junos OS Evolved version 22.2-EVO, update to version 22.2R1-S1-EVO, 22.2R2-EVO or later.
