A Stack-based Buffer Overflow vulnerability in the l2cpd daemon of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause a denial of service in Layer 2 control-plane processing via LLDP packets received on an interface configured for LLDP. Repeated triggering may disrupt LLDP and other Layer 2 control protocols across the device.
