QID 44027: Arista EOS Multiple Vulnerabilities (SA0084)

Arista EOS

Arista EOS is a fully programmable and highly modular, Linux-based network operation system, using familiar industry-standard CLI, and runs a single binary software image across the Arista switching family.

Affected EOS versions:
4.29.1F and below releases in the 4.29.x train
4.28.5.1M and below releases in the 4.28.x train
4.27.8.1M and below releases in the 4.27.x train
4.26.9M and below releases in the 4.26.x train
4.25.10M and below releases in the 4.25.x train
4.24.11M and below releases in the 4.24.x train
QID Detection Logic (Authenticated):
The check matches Arista EOS version retrieved via Unix Auth using "show version" command.

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.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.
