"The version of Junos OS installed on the remote host is affected by a vulnerability as referenced in the JSA73152
advisory.

  - A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in telemetry processing of Juniper
    Networks Junos OS allows a network-based authenticated attacker to flood the system with multiple
    telemetry requests, causing the Junos Kernel Debugging Streaming Daemon (jkdsd) process to crash, leading
    to a Denial of Service (DoS). Continued receipt and processing of telemetry requests will repeatedly crash
    the jkdsd process and sustain the Denial of Service (DoS) condition. (CVE-2023-44188)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
