      <title>CVE-2024-21593 — Junos OS: MX Series with MPC10, MPC11, LC9600, and MX304: A specific MPLS packet will cause a PFE crash</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-21593</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Juniper Networks Junos OS&lt;/p&gt;
&lt;p&gt;An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).&lt;/p&gt;
&lt;p&gt;If an attacker sends a specific MPLS packet, which upon processing, causes an internal loop, that leads to a PFE crash and restart. Continued receipt of these packets leads to a sustained Denial of Service (DoS) condition.
 
Circuit cross-connect (CCC) needs to be configured on the device for it to be affected by this issue.&lt;/p&gt;
&lt;p&gt;This issue only affects MX Series with MPC10, MPC11, LC9600, and MX304.&lt;/p&gt;
&lt;p&gt;This issue affects:
Juniper Networks Junos OS
21.4 versions from 21.4R3 earlier than 21.4R3-S5;
22.2 versions from 22.2R2 earlier than 22.2R3-S2;
22.3 versions from 22.3R1 earlier than 22.3R2-S2;
22.3 versions from 22.3R3 earlier than 22.3R3-S1
22.4 versions from 22.4R1 earlier than 22.4R2-S2, 22.4R3;
23.2 versions earlier than 23.2R1-S1, 23.2R2.&lt;/p&gt;</description>
