A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).

PTX3000, PTX5000, QFX10000, PTX1000, PTX10002, and PTX10004, PTX10008 and PTX10016 with LC110x FPCs do not support certain flow-routes. Once a flow-route is received over an established BGP session and an attempt is made to install the resulting filter into the PFE, FPC heap memory is leaked. The FPC heap memory can be monitored using the CLI command \"show chassis fpc\".

The following syslog messages can be observed if the respective filter derived from a flow-route cannot be installed.
