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.
The product parses a formatted message or structure, but it does not handle or incorrectly handles a length field that is inconsistent with the actual length of the associated data.
