A high rate of VLAN authentication attempts sent from an adjacent host on the local broadcast domain can trigger high memory utilization by the BBE subscriber management daemon (bbe-smgd), and lead to a denial of service condition. The issue was caused by attempting to process an unbounded number of pending VLAN authentication requests, leading to excessive memory allocation. This issue only affects devices configured for DHCPv4/v6 over AE auto-sensed VLANs, utilized in Broadband Edge (BBE) deployments. Other configurations are unaffected by this issue. Affected releases are Juniper Networks Junos OS: 15.1 versions before 15.1R6-S2, 15.1R7; 16.1 versions before 16.1R5-S1, 16.1R6; 16.2 versions before 16.2R2-S2, 16.2R3; 17.1 versions before 17.1R2-S5, 17.1R3; 17.2 versions before 17.2R2.
