Description
This security update for python-urllib3 addresses multiple resource exhaustion vulnerabilities related to decompression processes. The issues include unbounded decompression chains, excessive resource consumption from highly compressed data in the Streaming API, and during decompression of HTTP redirect responses. Additionally, a non-security issue disables response decompression with brotli due to a missing feature.
