Potential remote code execution in ruby-git

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.
