Summary

An Improper Check or Handling of Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS on QFX10002 allows an unauthenticated, adjacent attacker on the local broadcast domain sending a malformed packet to the device, causing all PFEs other than the inbound PFE to wedge and to eventually restart, resulting in a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue can only be triggered by sending a specific malformed packet to the device. Transit traffic does not trigger this issue. An indication of this issue occurring can be seen through the following log messages: fpc0 expr_hostbound_packet_handler: Receive pe 73? fpc0 Cmerror Op Set: PE Chip: PE0[0]: PGQ:mis
