PHP 5.5.2

CVE-2011-4718: A session fixation vulnerability in the Sessions subsystem in PHP, before 5.5.2, allows remote attackers to hijack web sessions by specifying a session ID.

CVE-2013-4248: The openssl_x509_parse function in openssl.c in the OpenSSL module in PHP before 5.4.18 and 5.5.x (before 5.5.2) does not properly handle a null character in a domain name in the Subject Alternative Name field of an X.509 certificate.
