Junos OS: EX4650 Series: Certain traffic received by the Junos OS device on the management interface may be forwarded to egress interfaces instead of discarded

Summary

Due to an Improper Initialization vulnerability in Juniper Networks Junos OS on EX4650 devices, packets received on the management interface (em0) but not destined to the device, may be improperly forwarded to an egress interface, instead of being discarded. Such traffic being sent by a client may appear genuine, but is non-standard in nature and should be considered as potentially malicious.
