patch 9.0.1833: [security] runtime file fixes Commit: https://github.com/vim/vim/commit/816fbcc262687b81fc46f82f7bbeb1453addfe0c Author: Christian Brabandt <cb@256bit.org> Date: Thu Aug 31 23:52:30 2023 +0200 patch 9.0.1833: [security] runtime file fixes Problem: runtime files may execute code in current dir Solution: only execute, if not run from current directory The perl, zig and ruby filetype plugins and the zip and gzip autoload plugins may try to load malicious executable files from the current working directory. This is especially a problem on windows, where the current directory is implicitly in your $PATH and windows may even run a file with the extension `.bat` because of $PATHEXT. So make sure that we are not trying to execute a file from the current directory. If this would be the case, error out (for the zip and gzip) plugins or silently do not run those commands (for the ftplugins). This assumes, that only the current working directory is bad. For all other directories, it is assumed that those directories were intentionally set to the $PATH by the user. Signed-off-by: Christian Brabandt <cb@256bit.org>
