| Doc Text: |
A flaw was found in Ruby. When compiling a specially crafted regular expression with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /#{input}/, a double free can occur when parsing a pattern that fails after an alternation. This double free causes memory corruption, potentially resulting in arbitrary code execution.
