An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX10000 Series allows a network based malicious user to cause a Denial of Service (DoS). If a specific valid IP packet is received and that packet needs to be routed over a VXLAN tunnel, this will result in a PFE wedge condition due to which traffic gets impacted. As this is not a crash and restart scenario, this condition will persist until the system is rebooted to recover. This issue affects Juniper Networks Junos OS on QFX10000: 20.3 version 20.3R1 and later versions; 20.4 versions before 20.4R3-S5; 21.1 versions before 21.1R3-S5; 21.2 versions before 21.2R3-S5; 21.3 versions before 21.3R3-S4; 21.4 versions before 21.4R3-S1; 22.1 versions before 22.1R3; 22.2 versions before 22.2R2; 22.3 versions before 22.3R1-S2, 22.3R2.
