Summary

A Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on MX Series allows an unauthenticated adjacent attacker to cause a Denial-of-Service (DoS). In a subscriber management scenario, login/logout activity triggers a memory leak, and the leaked memory gradually increments and eventually results in a crash.                 user@host> show chassis fpc                                        Temp    CPU Utilization (%)   CPU Utilization (%)   Memory     Utilization (%)                       Slot State       (C)     Total   Interrupt     1min   5min  15min    DRAM (MB)  Heap   Buffer                       2 Online         36       10         0          9     8     9        32768      26         0
