Debian: DSA-4467-1 Moderate Vulnerability in Vim Shell Commands

User "Arminius" discovered a vulnerability in Vim, an enhanced version of the
standard UNIX editor Vi (Vi IMproved). The "Common vulnerabilities and
exposures project" identifies the following problem:

Editors typically provide a way to embed editor configuration commands (aka
modelines) which are executed once a file is opened, while harmful commands
are filtered by a sandbox mechanism. It was discovered that the "source"
command (used to include and execute another file) was not filtered, allowing
shell command execution with a carefully crafted file opened in Vim.

For the stable distribution (stretch), this problem has been fixed in
version 8.0.0197-4+deb9u2.

We recommend that you upgrade your vim packages.
