Debian: DSA-4261-1 Critical: vim-syntastic Arbitrary Code Execution

Enrico Zini discovered a vulnerability in Syntastic, an addon
module for the Vim editor that runs a file through external checkersand displays any resulting errors. Config files were looked up in the
current working directory which could result in arbitrary
shell code execution if a malformed source code file is opened.

For the stable distribution (stretch), this problem has been fixed in
version 3.7.0-1+deb9u2.

We recommend that you upgrade your vim-syntastic packages.
