On Juniper Networks MX series, receipt of a stream of specific Layer 2 frames may cause a memory leak resulting in the packet forwarding engine (PFE) on the line card to crash and restart, causing traffic interruption. By continuously sending this stream of specific layer 2 frame, an attacker connected to the same broadcast domain can repeatedly crash the PFE, causing a prolonged Denial of Service (DoS). This issue affects Juniper Networks Junos OS on MX Series: 17.2 versions before 17.2R3-S4; 17.2X75 versions before 17.2X75-D105.19; 17.3 versions before 17.3R3-S7; 17.4 versions before 17.4R1-S3, 17.4R2; 18.1 versions before 18.1R2. This issue does not affect Juniper Networks Junos OS releases before 17.2R1.
