Arista Networks EOS Memory Exhaustion (SA0084)

high Nessus Plugin ID 179045

Language:

Synopsis

The version of Arista Networks EOS running on the remote device is affected by a memory exhaustion vulnerability.

Description

On affected platforms running Arista EOS with SNMP configured and the snmpd process is running, a specially crafted SNMP packet can cause a memory leak in the snmpd process. This may result in the snmpd processing being terminated (causing SNMP requests to time out until snmpd is automatically restarted) and potential memory resource exhaustion for other processes on the switch. The vulnerability does not have any confidentiality or integrity impacts to the system.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the patch or upgrade to a fixed version as referenced in the vendor advisory.
