Junos OS and Junos OS Evolved: With certain BGP options enabled, receipt of specifically malformed BGP update causes RPD crash
An Out-of-Bounds Read vulnerability in

the routing protocol daemon (rpd) of 

 Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.


This issue only affects systems configured in
      either of two ways:

    
    
        *  systems with BGP traceoptions enabled

        *  systems with BGP traffic engineering
          configured

    


This issue can affect iBGP and eBGP with 

any address family

 configured. The specific attribute involved is non-transitive, and will not propagate across a network.

This issue affects:

Junos OS: 



  *  All versions before 21.4R3-S8,
  *  22.2 before 22.2R3-S5,
