NVD Description
Note: Versions mentioned in the description apply only to the upstream node-websocket-driver package and not the node-websocket-driver package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, if this library is used with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size because the limit is checked against the message frames' length headers, which give the size of the compressed data, not the size after decompression in lib/websocket/driver/hybi.js. This can lead to applications accepting larger messages than expected and exceeding their intended resource usage. This issue is fixed in version 0.7.5.
