Eval injection vulnerability in the HttpCache class in HttpKernel in Symfony 2.x before 2.3.27, 2.4.x and 2.5.x before 2.5.11, and 2.6.x before 2.6.6 allows remote attackers to execute arbitrary PHP code via a language="php" attribute of a SCRIPT element.

The Security component in Symfony 2.0.x before 2.0.25, 2.1.x before 2.1.13, 2.2.x before 2.2.9, and 2.3.x before 2.3.6 allows remote attackers to cause a denial of service (CPU consumption) via a long password that triggers an expensive hash computation, as demonstrated by a PBKDF2 computation, a similar issue to CVE-2013-5750.
