Vulnerability Details:

CVE-ID: CVE-2013-4248

DESCRIPTION: PHP could allow a remote attacker to conduct spoofing attacks, caused by an error when handling certificates that contain hostnames with NULL bytes. By persuading a victim to visit a Web site containing a specially-crafted certificate, a remote attacker could exploit this vulnerability using man-in-the-middle techniques to spoof SSL servers.

CVSS Base Score: 4.3
