Description
This advisory documents the impact of a vulnerability in Arista's EOS software. Various issues with dnsmasq may result in the dns cache being poisoned by a malicious attacker. The impact is that other clients querying the EOS switch as a DNS server would receive invalid DNS records. This requires an optional configuration to be set in EOS to allow using the EOS switch as a DNS server. This issue may also be known as "DNSPooq" or "ICS-VU-668462" from different sources. This is an externally found vulnerability and is released as part of a coordinated effort with CERT and dnsmasq.
