Because the accumulator grows without bound, the multiplication is not constant time and one pass over N digits costs O(N squared). handle_data/2 prepends conn.buffer and re-parses from the start on every socket message, so a server that dribbles the digits out in small packets makes the client pay that cost repeatedly. A run of roughly 512,000 hex digits costs over ten seconds of CPU in a single pass, measured on stock defaults. The parser reaches this state after a valid status line and a complete, valid header section, so an intermediary inspecting only headers sees an ordinary 200 response.</p> <p>This issue affects mint: from 1.9.3 before 1.10.0.</p> <p>Inefficient Algorithmic Complexity vulnerability in elixir-mint mint allows a remote HTTP server to exhaust CPU on the client host and cause a denial of service.</p> <p>parse_hex_prefix/2 in lib/mint/http1/parse.ex folds each hex digit of a chunked response&#39;s chunk-size field into an arbitrary-precision accumulator with acc * 16 + digit and imposes no limit on the digit count.
