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 •

This advisory documents the impact of an internally found vulnerability in Arista EOS for security ACL bypass. The impact of this vulnerability is that the security ACL drop rule might be bypassed if a NAT ACL rule filter with permit action matches the packet flow. This could allow a host with an IP address in a range that matches the range allowed by a NAT ACL and a range denied by a Security ACL to be forwarded incorrectly as it should have been denied by the Security ACL. This can enable an ACL bypass. Este aviso documenta el impacto de una vulnerabilidad encontrada internamente en Arista EOS para omitir las ACL de seguridad. • https://www.arista.com/en/support/advisories-notices/security-advisory/15862-security-advisory-0078 • CWE-284: Improper Access Control •
