Details

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.
