CVE-2019-10912: Prevent destructors with side-effects from being unserialized

Other sources

In Symfony before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, it is possible to cache objects that may contain bad user input. On serialization or unserialization, this could result in the deletion of files that the current user has access to. This is related to symfony/cache and symfony/phpunit-bridge.

Possible deserialization side-effects in symfony/cache
