On affected platforms running Arista EOS with VXLAN configured, malformed or truncated packets received over a VXLAN tunnel and forwarded in hardware can cause egress ports to be unable to forward packets. The device will continue to be susceptible to the issue until remediation is in place. • https://www.arista.com/en/support/advisories-notices/security-advisory/18043-security-advisory-0089 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

On affected modular platforms running Arista EOS equipped with both redundant supervisor modules and having the redundancy protocol configured with RPR or SSO, an existing unprivileged user can login to the standby supervisor as a root user, leading to a privilege escalation. Valid user credentials are required in order to exploit this vulnerability. • https://www.arista.com/en/support/advisories-notices/security-advisory/16985-security-advisory-0082 • CWE-269: Improper Privilege Management •

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 •
