Affected packages

• RubyGems ruby_parser-legacy: <= 1.0.0 (no fix yet)

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.
