Description
A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of the Juniper Networks Junos OS on the MX Series platforms with Trio-based FPCs allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).
In case of channelized Modular Interface Cards (MICs), every physical interface flap operation will leak heap memory. Over a period of time, continuous physical interface flap operations causes local FPC to eventually run out of memory and crash.
Below CLI command can be used to check the memory usage over a period of time:
user@host> show chassis fpc
Temp CPU Utilization (%) CPU Utilization (%) Memory
Utilization (%)
Slot State (C) Total Interrupt 1min 5min
15min DRAM (MB) Heap Buffer
