What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

On affected Arista Wi-Fi access points with Captive Portal enabled, an unauthenticated wireless client connected to a Captive-Portal-enabled SSID can crash the portal service with a crafted HTTP request. This results in a temporary denial of service until the service automatically restarts. Remote code execution is not possible.
