A Missing Release of Memory after Effective Lifetime vulnerability in the BroadBand Edge subscriber management daemon (bbe-smgd) of Juniper Networks Junos OS on MX Series allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).

When all memory available to bbe-smgd has been consumed, no new subscribers will be able to login. The memory utilization of bbe-smgd can be monitored with the following show command: user@host> show system processes extensive | match bbe-smgd The below log message can be observed when this limit has been reached: bbesmgd[<PID>]: %DAEMON-3-SMD_DPROF_RSMON_ERROR: Resource unavailability, Reason: Daemon Heap Memory exhaustion This issue affects Junos OS on MX Series: * all versions before 22.4R3-S8, * 23.2 versions before 23.2R2-S5, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S2, * 24.4 versions before 24.4R2, * 25.2 versions before 25.2R2.
