Juniper Networks Junos OS Missing Release of Memory after Effective Lifetime Denial of Service
Description

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. expr_dfw_sfm_range_add:661 SFM packet-length Unable to get a sfm entry for updating the hw expr_dfw_hw_sfm_add:750 Unable to add the filter secondarymatch to the hardware expr_dfw_base_hw_add:52 Failed to add h/w sfm data. expr_dfw_base_hw_create:114 Failed to add h/w data. expr_dfw_base_pfe_inst_create:241 Failed to create base inst for sfilter 0 on PFE 0 for __flowspec_default_inet__ expr_dfw_flt_inst_change:1368 Failed to create __flowspec_default_inet__ on PFE 0 expr_dfw_hw_pgm_fnum:465 dfw_pfe_inst_old not found for pfe_index 0! expr_dfw_bp_pgm_flt_num:548 Failed to pgm bind-point in hw: generic failure expr_dfw_bp_topo_handler:1102 Failed to program fnum. expr_dfw_entry_process_change:679 Failed to change instance for filter __flowspec_default_inet__.
