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.

For the stable distribution (jessie), these problems have been fixed in
