Description
On affected platforms running Arista EOS, maliciously formed UDP packets with source port 3503 may be accepted by EOS. UDP Port 3503 is associated with LspPing Echo Reply. This can result in unexpected behaviors, especially for UDP based services that do not perform some form of authentication.
