"Vim is an almost compatible version of the UNIX editor Vi. Many new features have been added: multi-level undo, syntax highlighting, command line history, on-line help, spell checking, filename completion, block operations, etc.'' Improper quoting in some parts of Vim written in the Vim Script can lead to arbitrary code execution upon opening a crafted file.
