Junos OS: EX Series, QFX Series: If the same egress filter is configured on both an IRB and a physical interface one of those is not applied

An Incorrect Initialization of Resource vulnerability in the packet forwarding engine (pfe) of Juniper Networks Junos OS on specific EX Series and QFX Series device allows an unauthenticated, network-based attacker to cause an integrity impact to downstream networks.

When the same family inet or inet6 filter is applied on an IRB interface and on a physical interface as egress filter on EX4100, EX4400, EX4650 and QFX5120 devices, only one of the two filters will be applied, which can lead to traffic being sent out one of these interfaces which should have been blocked.

This issue affects Junos OS on EX Series and QFX Series:
  *  23.4 version 23.4R2-S6,
  *  24.2 version 24.2R2-S3.


No other Junos OS versions are affected.
