Summary

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.

Risk Assessment

The attack can cause disruptions in Layer 2 protocols, potentially affecting network stability and service availability.

Recommendation

Apply security updates provided by Juniper Networks and restrict trusted sources of LLDP packets on interfaces.
