PYSEC-2020-29

Quick fix

PYSEC-2020-29 — brotli: upgrade to the fixed version with the command below.

pip install --upgrade 'brotli>=1.0.8'

Details

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.
