Description

This advisory documents a vulnerability in Arista's EOS for device configurations using VxLAN Routing and VRFs. On impacted devices, malformed packets could be incorrectly forwarded across VRF boundaries when non-default VRFs are configured. This issue affects UDP traffic and will fail to complete the three-way handshake for TCP traffic. The vulnerability was discovered internally and Arista is not aware of any malicious uses in customer networks.
