  "summary": "Updated python-hpack packages fix a security vulnerability",
  "details": "An issue was found in the python-hyper/hpack library, most commonly used as\na downstream dependency of the python-hyper/h2 library (an HTTP/2 client\nand server implementation). Unbounded variable integer decoding can\ncause run-away computation on malformed input leading to O(n^2) runtime,\neffectively blocking further processing with large enough unsanitized\ninput.\nA fix python-hyper/hpack v4.2.0 restricts variable integer decoding to\nuint32 to prevent run-away computation.\n",
