CWE-20  (opens in a new tab)

How to fix?

Upgrade php to version 5.4.18 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. 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 '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
