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 access points configured with VXLAN tunnelling and L2-proxy (a specific configuration unique to the VESPA use-case), a wireless client associated to the tunnelled SSID can send a crafted packet, causing the access point to reveal memory contents in network traffic. No write primitive or remote code execution is possible.
