Descripción
*** Pendiente de traducción *** An Out-of-bounds Write vulnerability in the SNMP daemon (snmpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated network-based attacker sending specific valid SNMPv3 queries to trigger a memory leak. Over time, continuous receipt of these queries will result in snmpd process memory exhaustion, resulting in a process crash and restart, impacting the ability to monitor the system via SNMP.<br />
<br />
Memory usage can be monitored using the following command:<br />
<br />
user@device> show system processes extensive | match snmpd<br />
<br />
<br />
