Alpine: multiple brotli packages, multiple py3-brotli packages: security update to 1.0.9-r0

medium Tenable Self-Hosted Container Security Plugin ID 423759

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2020-8927)
