  - An Improper Check or Handling of Exceptional Conditions vulnerability in packet processing of Juniper
    Networks Junos OS on QFX10002 allows an unauthenticated, adjacent attacker on the local broadcast domain
    sending a malformed packet to the device, causing all PFEs other than the inbound PFE to wedge and to
    eventually restart, resulting in a Denial of Service (DoS) condition. Continued receipt and processing of
    this packet will create a sustained Denial of Service (DoS) condition. (CVE-2023-28959)

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