NVD Description

Note: Versions mentioned in the description apply only to the upstream airflow-2 package and not the airflow-2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

hpack is an HTTP/2 Header Encoding for Python. Prior to version 4.2.0, unbounded variable integer decoding can cause run-away computation on malformed input leading to O(n^2) runtime, effectively blocking further processing with large enough unsanitized input. A fix is available in python-hyper/hpack v4.2.0 to restricted variable integer decoding to uint32 to prevent run-away computation. As a workaround, sanitize input to hpack decoder for long sequences of 0xFF values to prevent malicious use.
