title: brakeman world writable files allow local privilege escalation

description: |
  The ruby_parser-legacy (aka legacy) gem 1.0.0 for Ruby allows local
  privilege escalation because of world-writable files. For example,
  if the brakeman gem (which has a legacy dependency) 4.5.0 through 4.7.0 is used,
  a local user can insert malicious code into the
  ruby_parser-legacy-1.0.0/lib/ruby_parser/legacy/ruby_parser.rb file.
