NVD Description

Note: Versions mentioned in the description apply only to the upstream commercial-gitlab-rails-ee-19.2 package and not the commercial-gitlab-rails-ee-19.2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Impact

If this library is used in tandem 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. This is because this limit is checked against the message frames' length headers, which give the size of the compressed data, not the size after decompression. This can lead to applications accepting larger messages than expected and exceeding their intended resource usage.

Patches

The issue has been patched in version 0.8.1, by checking the length of messages after they are processed by incoming extensions. All users should upgrade to this version.

Workarounds

No known workarounds exist.
