### Description

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.This issue affects Junos OS Evolved on ACX7000 Series:  *  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,   *  22.4-EVO versions before 22.4R3-S2-EVO,   *  23.2-EVO versions before 23.2R2-EVO,   *  23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO.
