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.
