CVE-2023-36838

An Out-of-bounds Read vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series allows a local, authenticated attacker with low privileges, to cause a Denial of Service (DoS).<br /> <br /> If a low privileged user executes a specific CLI command, flowd which is responsible for traffic forwarding in SRX crashes and generates a core dump. This will cause temporary traffic interruption until the flowd process is restarted automatically. Continued execution of this command will lead to a sustained DoS.<br /> <br /> This issue affects Juniper Networks Junos OS on SRX Series:<br /> All versions prior to 20.2R3-S7;<br /> 20.3 version 20.3R1 and later versions;<br /> 20.4 versions prior to 20.4R3-S6;<br /> 21.1 versions prior to 21.1R3-S5;<br /> 21.2 versions prior to 21.2R3-S4;<br /> 21.3 versions prior to 21.3R3-S4;<br /> 21.4 versions prior to 21.4R3-S3;<br /> 22.1 versions prior to 22.1R3-S1;<br /> 22.2 versions prior to 22.2R3;<br /> 22.3 versions prior to 22.3R2;<br /> 22.4 versions prior to 22.4R1-S1, 22.4R2.<br />
