SCA: security update for symfony/form, symfony/symfony (GHSA-x3cf-w64x-4cp2)

medium Tenable Cloud Security Plugin ID 434379

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An issue was discovered in Symfony 2.7.x before 2.7.50, 2.8.x before 2.8.49, 3.x before 3.4.20, 4.0.x
 before 4.0.15, 4.1.x before 4.1.9, and 4.2.x before 4.2.1. When using the scalar type hint `string` in a
 setter method (e.g. `setName(string $name)`) of a class that's the `data_class` of a form, and when a file
 upload is submitted to the corresponding field instead of a normal text input, then
 `UploadedFile::__toString()` is called which will then return and disclose the path of the uploaded file.
 If combined with a local file inclusion issue in certain circumstances this could escalate it to a Remote
 Code Execution. (CVE-2018-19789)
