Two vulnerabilities were
discovered in Symfony, a PHP framework.
CVE-2016-1902
Lander Brandt discovered that the class SecureRandom might generate
weak random numbers for cryptographic use under certain settings. If
the functions random_bytes() or openssl_random_pseudo_bytes() are not
available, the output of SecureRandom should not be consider secure.
CVE-2016-4423
Marek Alaksa from Citadelo discovered that it is possible to fill up
the session storage space by submitting inexistent large usernames.
