Symfony version(s) affected

3.4 | 4.4

Description

We're using \Symfony\Component\Process\PhpExecutableFinder in Drupal's Upgrade Status module to execute PHPStan from a UI. In different environments leveraging Plesk or ISPConfig, the returned path from \Symfony\Component\Process\PhpExecutableFinder::find is a directory.

How to reproduce

I haven't been able to reproduce since I do not have access to a Plesk server. But directories are technically executable.

Possible Solution

The checks for is_exectuable may need a !is_dir check?
