What to Know

A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream.

Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1. (NVD)

What to Do

Monitor Siemens, Microsoft, nodejs, python-hyper, istio, anthropic, envoyproxy, tianocore, duckdb, clickhouse, Apache, mcmilk, 7-zip, and andybalholm's web pages for any future patch releases. See vendor advisory link below.
