Summary
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.
