CVE-2024-39538

A Buffer Copy without Checking Size of Input vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated, adjacent attacker to cause a 

Denial-of-Service (DoS).When multicast traffic with a specific, valid (S,G) is received, evo-pfemand crashes which leads to an outage of the affected FPC until it is manually recovered.

  *  All versions before 21.2R3-S8-EVO,
  *  21.4-EVO versions before 21.4R3-S7-EVO,
  *  22.2-EVO versions before 22.2R3-S4-EVO,
  *  22.3-EVO versions before 22.3R3-S3-EVO,
