Junos OS Evolved: Specific TCP traffic causes OFP core and restart of RE





An Improper Handling of Syntactically Invalid Structure vulnerability in Object Flooding Protocol (OFP) service of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).

On all Junos OS Evolved platforms, when specific TCP packets are received on an open OFP port, the OFP crashes leading to a restart of Routine Engine (RE). Continuous receipt of these specific TCP packets will lead to a sustained Denial of Service (DoS) condition.





This issue affects:

Juniper Networks Junos OS Evolved



  *  All versions earlier than 21.2R3-S7-EVO;
  *  21.3 versions earlier than 21.3R3-S5-EVO ;
