  "details": "Uncontrolled Resource Consumption vulnerability in the Elixir standard library's Version module allows an attacker who controls a version string to cause a denial of service through CPU and memory exhaustion.  The version parser converts numeric version components (major, minor, patch and numeric pre-release/build identifiers) to integers without bounding their length. A single large all-digit component therefore forces a super-linear, non-yielding base-10 to arbitrary-precision integer conversion (String.to_integer/1, i.e. :erlang.binary_to_integer/1) that pins a BEAM scheduler, and a larger component raises an uncaught SystemLimitError that crashes the calling process. A single moderately sized string (around one megabyte) is enough; no authentication is required.  This is reachable from the public entry points Version.parse/1, Version.parse!/1, Version.match?/3, Version.compare/2, and Version.parse_requirement/1, which applications routinely call on untrusted input such as HTTP parameters, dependency-manifest fields, and package metadata.  This vulnerability is associated with program files lib/version.ex and program routines 'Elixir.Version.Parser':parse_digits/2.  This issue affects Elixir: from 1.5.0 before 1.20.1.",
