On affected platforms running Arista EOS with automatic certificate management configured and automatic Certificate Authority (CA) certificate retrieval enabled, a malicious packet may cause the AutoCertMgmt process to be terminated unexpectedly. Managed X.509 certificates will not be renewed automatically and may eventually expire, potentially disrupting TLS-dependent services.
