# CVE-2024-21612

> 7.5 HIGH

## Beschreibung

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 ;
  *  21.4 versions earlier than 21.4R3-S5-EVO;
  *  22.1 versions earlier than 22.1R3-S4-EVO;
  *  22.2 versions earlier than 22.2R3-S3-EVO ;
