Description

This security bulletin contains information about 1 vulnerability.


1) Improper handling of syntactically invalid structure (CVE-ID: CVE-2024-21612)

CWE-ID: CWE-228 - Improper Handling of Syntactically Invalid Structure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of syntactically invalid structure error in Object Flooding Protocol (OFP) service. A remote non-authenticated attacker can 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.
