What to Know

A flaw was found in Vim's netrw plugin. A crafted filename containing quote characters and expression fragments can break out of the quoted context during mark/unmark operations, allowing arbitrary Vimscript execution. This can be leveraged to run shell commands with the privileges of the user running Vim. (NVD)

What to Do

Monitor Red Hat's and vim's web pages for any future patch releases.
