It's just a particular binary build of vim. The vim Debian source package
builds vim several times with different options: vim.tiny is the
smallest, with no GUI and no Perl/Python/Ruby/Lua bindings.
Fedora /bin/vi is a similar small vim build.

I would be quite surprised if there are any vulnerabilities in vim.tiny
that aren't also present in the larger builds like vim.gtk3.
In particular, swap file handling and its interaction with setuid are
almost certainly the same in all builds of the same vim source code.
