### Summary Symfony 1 has a gadget chain due to vulnerable Swift Mailer dependency that would enable an attacker to get remote code execution if a developer unserialize user input in his project. ### Details This vulnerability present no direct threat but is a vector that will enable remote code execution if a developper deserialize user untrusted data. For example: ```php public function executeIndex(sfWebRequest $request) { $a = unserialize($request->getParameter('user')); } ``` We will make the assumption this is the case in the rest of this explanation. Symfony 1 depends on Swift Mailer which is bundled by default in `vendor` directory in the default installation since 1.3.0. Swift Mailer classes implement some `__destruct()` methods like for instance `Swift_KeyCache_DiskKeyCache` : ```php public function __destruct() { foreach ($this->_keys as $nsKey=>$null) { $this->clearAll($nsKey); } } ``` This method is called when php destroy the object in memory. However, it is possible to include any object type in `$this->_keys` to make PHP access to another array/object properties than intended by the developer. In particular, it is possible to abu
