      <title>CVE-2023-22403 — Junos OS: QFX10K Series: An ICCP flap will be observed due to excessive specific traffic</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2023-22403</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Juniper Networks Junos OS&lt;/p&gt;
&lt;p&gt;An Allocation of Resources Without Limits or Throttling vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS).&lt;/p&gt;
&lt;p&gt;On QFX10K Series, Inter-Chassis Control Protocol (ICCP) is used in MC-LAG topologies to exchange control information between the devices in the topology. ICCP connection flaps and sync issues will be observed due to excessive specific traffic to the local device.&lt;/p&gt;
&lt;p&gt;This issue affects Juniper Networks Junos OS on QFX10K Series:&lt;/p&gt;
&lt;p&gt;*  All versions prior to 20.2R3-S7;
  *  20.4 versions prior to 20.4R3-S4;
  *  21.1 versions prior to 21.1R3-S3;
  *  21.2 versions prior to 21.2R3-S1;
  *  21.3 versions prior to 21.3R3;
  *  21.4 versions prior to 21.4R3;
  *  22.1 versions prior to 22.1R2.&lt;/p&gt;</description>
