A buffer overflow exists in the Brotli library versions prior to 1.0.8
where an attacker controlling the input length of a “one-shot”
decompression request to a script can trigger a crash, which happens when
copying over chunks of data larger than 2 GiB. It is recommended to update
your Brotli library to 1.0.8 or later. If one cannot update, we recommend
to use the “streaming” API as opposed to the “one-shot” API, and impose
chunk size limits.
