On the affected platforms running EOS, a malformed DHCP packet might cause the DHCP relay agent to restart. • https://www.arista.com/en/support/advisories-notices/security-advisory/17445-security-advisory-0087 • CWE-755: Improper Handling of Exceptional Conditions •

On affected platforms running Arista EOS, an authorized attacker with permissions to perform gNMI requests could craft a request allowing it to update arbitrary configurations in the switch. This situation occurs only when the Streaming Telemetry Agent (referred to as the TerminAttr agent) is enabled and gNMI access is configured on the agent. Note: This gNMI over the Streaming Telemetry Agent scenario is mostly commonly used when streaming to a 3rd party system and is not used by default when streaming to CloudVision • https://www.arista.com/en/support/advisories-notices/security-advisory/17250-security-advisory-0086 • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •

On affected platforms running Arista EOS with SNMP configured, a specially crafted 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. • https://www.arista.com/en/support/advisories-notices/security-advisory/17239-security-advisory-0084 • CWE-401: Missing Release of Memory after Effective Lifetime •

For certain systems running EOS, a Precision Time Protocol (PTP) packet of a management/signaling message with an invalid Type-Length-Value (TLV) causes the PTP agent to restart. Repeated restarts of the service will make the service unavailable. • https://www.arista.com/en/support/advisories-notices/security-advisory/15439-security-advisory-0076 • CWE-400: Uncontrolled Resource Consumption CWE-1284: Improper Validation of Specified Quantity in Input •

A vulnerability has been found in the implementation of the Label Distribution Protocol (LDP) protocol in EOS. Under race conditions, the LDP agent can establish an LDP session with a malicious peer potentially allowing the possibility of a Denial of Service (DoS) attack on route updates and in turn potentially leading to an Out of Memory (OOM) condition that is disruptive to traffic forwarding. Affected EOS versions include: 4.22 release train: 4.22.1F and earlier releases 4.21 release train: 4.21.0F - 4.21.2.3F, 4.21.3F - 4.21.7.1M 4.20 release train: 4.20.14M and earlier releases 4.19 release train: 4.19.12M and earlier releases End of support release trains (4.18 and 4.17) Se ha encontrado una vulnerabilidad en la implementación del protocolo Label Distribution Protocol (LDP) en EOS. En condiciones de carrera, el agente de LDP puede establecer una sesión de LDP con un peer malicioso, permitiendo potencialmente la posibilidad de un ataque de Denegación de Servicio (DoS) sobre las actualizaciones de ruta y, a su vez, conllevando potencialmente a una condición Out of Memory (OOM) que es perjudicial para el reenvío de tráfico. Las versiones EOS afectadas incluyen: tren de publicaciones de 4.22: 4.22.1F y versiones anteriores; tren de publicaciones de 4.21: 4.21.0F hasta 4.21.2.3F, 4.21.3F hasta 4.21.7.1M; tren de publicaciones de 4.20: 4.20.14M y versiones anteriores; tren de publicaciones de 4.19: 4.19.12M y versiones anteriores; trenes de publicaciones de fin de soporte (4.18 y 4.17) • https://www.arista.com/en/support/advisories-notices https://www.arista.com/en/support/advisories-notices/security-advisories/8321-security-advisory-42 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
