GHSA-pfpr-3463-c6jh ruby-git has potential remote code execution vulnerability

• RubyGems git: >= 1.2.0, < 1.13.0 → fixed in 1.13.0

The git gem, between versions 1.2.0 and 1.12.0, incorrectly parsed the output of the `git ls-files` command using `eval()` to unescape quoted file names. If a file name was added to the git repository contained special characters, such as `\n`, then the `git ls-files` command would print the file name in quotes and escape any special characters. If the `Git#ls_files` method encountered a quoted file name it would use `eval()` to unquote and unescape any special characters, leading to potential remote code execution. Version 1.13.0 of the git gem was released which correctly parses any quoted file names.
