Vulnerability Details CVE-2024-21612
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.
