Upgrade symfony/symfony to 2.1.5
symfony/symfony fixed: Latest secure release 
Upgrade symfony/symfony to Latest secure release
symfony/symfony fixed: 2.0.20 
Upgrade symfony/symfony to 2.0.20
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for symfony/symfony

How to Check if You Are Affected

To determine whether your application is affected by CVE-2012-6432, inspect your project dependencies for Symfony/symfony:
