Description
This advisory documents the impact of a vulnerability in Arista's EOS involving crossing VLAN boundaries in X-series platforms. In EVPN VxLAN setups, the effect of this vulnerability is that specific malformed packets can lead to incorrect MAC to IP bindings and as a result packets can be incorrectly forwarded across VLAN boundaries. This can result in traffic being discarded on the receiving VLAN. This issue was discovered internally and Arista is not aware of any malicious uses of this issue in customer networks.
