CyberRota Analysis
AI-GeneratedThe vulnerability in the elixir-mint library allows a remote HTTP server to exploit the lack of limits on header and trailer field accumulation, leading to potential memory exhaustion on the client host. This can result in a denial of service, as the application using Mint can be terminated by the operating system's out-of-memory handler. Organizations utilizing mint versions from 0.1.0 to before 1.9.2 should prioritize patching this vulnerability to prevent service disruptions.

Original NVD Description
Allocation of resources without limits vulnerability in elixir-mint mint allows a remote HTTP server to exhaust memory on the client host and cause a denial of service. The Mint.HTTP1.decode_headers/5 and Mint.HTTP1.decode_trailer_headers/4 functions in lib/mint/http1.ex accumulate every parsed response header and chunked-trailer field into a per-request list that persists across incoming TCP segments as request.headers_buffer, and only clear it when the terminating blank line is received. The section has no cap on the number of headers or on total bytes, and the underlying :erlang.decode_packet(:httph_bin, binary, []) parser is invoked with an empty option list so its per-line and per-packet size limits also default to unlimited. A malicious HTTP server (reachable directly, via an attacker-controlled redirect, via SSRF, or via a man-in-the-middle) can stream complete header lines (or, after a chunked body, complete trailer lines) indefinitely without ever emitting the terminating blank line. The connection state grows without bound until the BEAM node is killed by the operating system's out-of-memory handler, taking down the entire application that uses Mint as an HTTP client. This issue affects mint: from 0.1.0 before 1.9.2.
