An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600 allows a adjacent attacker to send specific traffic, which leads to packet flooding, resulting in a Denial of Service (DoS).

When a specific IGMP packet is received in an isolated VLAN, it is duplicated to all other ports under the primary VLAN, which causes a flood.

This issue affects QFX5000 series, EX2300, EX3400, EX4100, EX4400 and EX4600 platforms only.

This issue affects Juniper Junos OS on on QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600:

All versions prior to 20.4R3-S5;
21.1 versions prior to 21.1R3-S4;
21.2 versions prior to 21.2R3-S3;
21.3 versions prior to 21.3R3-S5;
21.4 versions prior to 21.4R3-S2;
22.1 versions prior to 22.1R3;
22.2 versions prior to 22.2R3;
22.3 versions prior to 22.3R2.
